Great game design!
Here's some feedback if you want it:
(If you don't want it, just message me and I'll remove it)
The levels are feel very nicely designed,
The concepts are presented in a nicely increasing level of difficulty.
I like the hints, they really match with the art style and I always understood what to do without it feeling like i'm being explicitly told.
The trail at the back of the character is a really nice touch.
The reset animation on green spikes with the sfx is really well done.
Checkpoints would be appreciated but maybe it's just cuz i'm a wuss 😆 (e.g. at the "good luck" at level 7 for e.g., I gave up on level 7, it's mean :C)
Level 8 was really cool, creative way of using the tools.
9, 10 really hard.
Bugs?:
Level 4 felt really inconsistent to me :c I felt as if I was doing the right thing but it didn't always hurt me. AH, I think I figured it out(?): The center of the character has to touch, I don't seem to take damage if the side of Blue (I'm calling the character Blue) touches the ground first.
A bug?: If I jump when there is a platform directly above me, I cannot seem to be able to jump anymore (unless I restart).
I was also sometimes able to double jump/jump mid air. AH: figured it out, it was actually a feature!(?)
All in all, good stuff.
Thank you for sharing!
