the boss is really easy to abuse you need a cool down period after you jump on him so you cant just get him stuck in a loop, the game is really well presented i love the sprite art and tons of ways you can use your roll to interact with things, wall jumping feels great if not a bit tricky, the enemies you bounce off confused my for a sec but i guess its just a placeholder sprite??
otherwise holy shit this is great
cant wait to see more of this is you plan on that this seems awesome, although i think you should maybe add a bit of null space where the sprite wont flip when at reallly low levels of speed to avoid weird constant back and fourth fliping
The stupidest shit is always the best, I genuinely played this shit for probably an unreasonable amount of time this has no right to actually be fun.
good game, physics mess up sometimes, there's a bug in act 2 where you clip through the floor, and one in act 1 with the crab robots where they keep shooting forever and stop moving.
and one bug where you can get hit on a spike and get hit again in like a millisecond even if you collect any rings you still die, its a fun game tho.
the level design in act 2 is unfair in one point where you have to take a leap of faith and then you get bounced over directly into an area that will either have you
-fall on a spike
-fall onto an enemy
-get flung into another enemy
act has a significant difficulty spike to me.
