Level design is reminiscent of the platforms in Contra.
The jump mechanic could use some tweaking. I feel like the jump and fall speeds are both a bit too fast.
Collision needs more work, btw; I often get "stuck" inside blocks. Also, I can get to the next map by glitching through the ceiling and walking on the "roof". On the last map, I think I glitched into an out-of-bounds area, which caused all levels to blink. Fun stuff.
Hope to see you in future game jams ^_^
