This is pretty fun, for the first few seconds I thought it was kinda clunky and I kinda felt too restricted, but I got over that quickly and I found it to be rather exciting. I was well entertained for quite a while, very nice job! Not a thing I encountered ever really made me not want to keep playing.
Edit: whoops, I didn't notice there was an even more recent version >_< sorry. Fixed most of this though.
Good:-The fuel bars blink with text, which is interesting. It gets my attention enough to tell me something has changed, though is not too distracting.
-The trick system doesn't feel as strict as I expected it to be. At first I thought I had to be facing forward perfectly on landing in order to not get hurt, but it is pleasingly loose in that respect.
-The tricks are slow enough where you fear doing one because you might not making it all the way around in time to land, making it quite a challenge. (I didn't realize at that time you could let go of X and spin back >_<)
-Not always caring that you can't land a trick and kinda just trading in shield for boost anyway
-I really like how limited the number of graphics are. Its really just you, the land, then the trees and meteors. I don't really know why I like this but it feels simple and clean. Fits well with the techy style. (That was 0.5.2 but it still stands, though I kinda preferred the simple, white ship)
-Trees falling over and creating more of a problem by being bigger and more in the way.
-Being able to see meteors coming to avoid them
-Seeing meteors coming and still not being able to predict anything since they knock trees over in your way.
-The pop-up text makes everything feel a lot more active.
-The whole background and terrain is really awesome in my opinion. Even though when I focus on the mountains I begin to see errors, but I still didn't care. The checkered grass and the smooth mountains look really nice together.
-It being possible to miss the refuel points. (And not being able to go back for them)
-The HUD zooming out as you boost. Though I think this effect would be made a little better if the HUD went back to the angled text that it was like in the 0.5.1 build
-The entire GUI is a lot better in the latest version. I didn't like how things were 3D in the menu but 2D in the HUD in 0.5.2, but the menu is very well done in the latest version.
-Those pixely shield collision graphics are amazing.
Bad:-Didn't realize that there were even tricks at first. Blew through the tutorial too fast (may be my own fault) and went to play. Ran out of boost and just kept going. Strangely though, I was still kept entertained, so this is both bad and good. (Note, that was when playing with 0.5.2's tutorial)
-I like how the new menu makes the fuel, boost, and shield readily available for the eye, but now the other three indicators are completely off radar. I can't even remember what those were for and I just played 30seconds ago. I almost prefer the old layout better, especially the angled numbers and such, they fit nicely in terms of the sorta sharp theme.
-Not being able to jump without boost. I've not even managed to get adequate air off of just speeding off a hill to get any tricks in without any boost yet.
-Tricks just feel kinda off in terms of gameplay, I would find them a lot more fun if they were quicker even though being quicker would kinda contradict with something I said in the good section. But they don't really fit in the theme once you think about it, you're a jet speeding across a terrain as fast as possible avoiding meteors, but doing tricks is rather slow and arduous. Maybe you could try splitting it, so that every time you press the arrow key (with x) you do one trick. And every trick consists of doing maybe 5 quick spins before slowing down to face forward, that way it will still feel fast while keeping the risk of not having enough time to do the trick.
-It'd probably be a hassle to fix, but landing on top of a meteor seems to hurt you regardless of whether it should. I don't know if this should even be fixed but I thought it might make it flow a bit smoother if you could land on a meteor without worry and just keep speeding through. Though at the same time I also like the fact that you can't because it forces you into panic sometimes when you know there's this great big rock in the way of your landing.
-It took me a really long time to figure out that you could let go of X to stop a trick and save yourself. Would have been really handy to know. Also, it would probably be better if you just had it so that it spun back if you let go of the arrow since letting go of X kinda breaks the flow of the game.
-The newest meteor crashing graphic is kinda distracting, though I got used to it kinda quickly
-I had no idea there was a pause button for the longest time.
-The tutorial still needs to say that letting go of X will right you.
-The newest ship graphic doesn't really fit with everything else. The landscape is kinda plain with one-color skins (which I like) but the new ship is really detailed and colorful, which is kinda strange.
Random Recommendations-It might be a good idea to make it so that the fuel resuppliers get further and further from each other as you progress so that you are forced to maintain a high speed. It would be incredibly difficult to get very far, and also to balance it out so that it is even possible (with all the things slowing you down), so maybe that'd be like a hard mode? also with that barrage of small asteroids that Inanimate suggested, that'd be cool.
Bugs:I played this on the 0.5.1 version for a few minutes and didn't encounter anything, but within seconds on 0.5.2 I got some strange ones. Though they didn't happen very frequently at all.
Edit: Derpity derp, could probably ignore all these as they are all in 0.5.2, I don't know if they are in the latest.
-I went really fast off a hill and started doing tricks and ended up past the left map boundaries and fell off. I was also quite a ways up high so that might have something to do with it.
-I noticed some trees that were upright and straight floating above a landed meteor that looked almost as though they were placed there. I can't be certain they didn't just fly up there on impact, but there were two of them making it hard to believe they actually landed straight up like that.
-I ran out of shield and triggered the damaged fire particle effects, but then hit a shield boost during the midst of it and got healed however the particles still lasted.
-I Hit something right before going up a slope and lost all momentum. Started going backwards and soon after fell through the floor and out of the map. Couldn't do it again though.
(bugs in the latest version)
-The terrain occasionally overlaps the GUI in the corners. Like the lowest corners of the fuel bars would intersect with the ground and be behind it.
-Music off button in the menu doesn't do anything
This is a lot more text than I intended when I started writing, and while I'm writing this line I still don't even feel half way through...
Effin' heck yeah, that was a lot longer than I intended >_<Also, what exactly does "Bt" stand for under the boost bar? BoosT?
