The Sprite work here is very nice and charming!! I can totally see the ENA inspiration too.
the controls are mostly pretty good but I think you should have a look into coyote time to make it more smooth, but apart from that pretty nice and I like that the rabbits boost your jump height a bit it seems. it ties the collectathon aspect to the platforming style quite nicely.
The style of the music fits the vibe of the character but I would like if the loop was longer and also and the second level it appears to be clashing restarting over and makes it hard for me to continue playing.
but pretty good effort all round though!! :-D
