It's a decent game, although the name instantly made me think it was going to be Halo-themed.
My only big suggestion would be to give the player far more control. The jump was so floaty that I couldn't really plan ahead because by the time an obstacle showed up, I was already in the air heading for it.
I feel like the game should have stronger gravity and/or the character should jump higher/lower depending on how long I hold the jump button. Another thing I kept wanting was for the button to make the character fall faster when pressed in the air, but I'm not sure if that should be in addition to gravity and variable jump height, or instead of them. It really depends on the feeling you're going for and might take some more play-testing.
Also, at least one wall (in level 2) seems unavoidable, which is a bit annoying. It should be the player's fault if they hit a wall, not the level's.
Two issues that aren't as design-related:
-The music loop is very short. Considering the levels aren't that long, it shouldn't be too difficult to make a music track that lasts the entire run.
-Easy mode seems so easy that I'm not sure it's even worth having in the game. I didn't try the other difficulties because of the lack of jump control.
I also agree with frik's suggestions.
Halo-themed
.. Its just a codename... If i'm to name it RVB it won't appear in search engines for centuries
-"jump higher/lower depending on how long I hold the jump button" .. That's a neat suggestion .. I will try that one ..
& will also look into changing the gravity & stuffs..I wanted to keep the rules simple that's why i did that way ..Don't know how the players react to it ...
(in level 2) seems unavoidable .. yes .. many of them were intentional ..(since both players are likely to encounter it, its a fifty fifty .. i think) ..Will look more into it..
I too felt easy mode was too easy (AI is so Dumb).. Maybe i'll retain only medium & hard mode i guess...
Thanks for the hell lot of constructive feedbacks .. & for giving me a lot more to work on..
