Just tried the new build (you've got to tell me when you release them, man! :O)!
The bigger areas really let you explore the jumping mechanics, and it's giving me a Super Meat boy-feel. Which is a very good thing!
I just can't get over how delicious the grass looks when you touch it...so smooth

A downside with having such huge ares visible at the screen at one time, is that those previously mentioned pixels don't get the visibility I feel they deserve, and also, it slightly removes the feeling of exploration..., though that could probably be fixed through just making huge fucking dungeons!

What I'm wondering most of all is, what approach will you take from here?
Will you make a metroidvania, where the focus is exploration and combat, or are you going with the Super Meat Boy speedrun-gameplay which seemed to get spotlight in this last build?
You could of course go in the direction VVVVV took; with a big map to explore, and areas that required precision-platforming to pass.
I, for one, vote for much explorations. My fingers are tingly from hunger after more of this world; I want to see more, and I want to to be a world, and not just an arrangement of skill-based arena maps.
Just my opinions, anyway

Looking forward to seeing more! Let me know!
