Quite a nice game... had to stop in lvl 5... I think I had 86 there? Stoped somehwere between 3 and 400. The meteros really felt quite unfair!
I think there was some triggersbox, but idk. They just felt unfair :D
Aside of that I like that the game escaleted a bit, maybe it would have been nice to tell the player whats happening. In lvl 3(?) I didnt get that the ground was heating me, thought I caused it by my actions so I tried to calm and and was confuse when I died at the elevaters despite doing nothing :D
What else to say... the graphics are okay, but could be better. Same for sounds/music...
Nice little game for a jam! Also thought at first I can double jump, was the walljump mentioned somewhere?
