I thought this was an incredible game. Well done!
Art direction is super great. I love the afterimage after you jump. Controls feel a bit unintuitive at first, but feels pretty nice afterwards. The difficulty curve got really steep at some point for me haha.
The only I kinda didn't like was the "rage game" aspect of it where you drop a bunch of child monkeys when you hit a spike. The game doesn't spell out what happens with them (I haven't been able to beat the game yet), but i always feel like I have to climb down to get them haha.
Sounds were great too. Only thing was a bit of a nitpick is when the music loop, there's a bit of a weird cut and stop.
Overall this is a super polished entry. Great job!
