I won! o//
Well, nice platformer, it reminds me of modern classics like SuperMeat Boy and the like. at first, I thought it would be more of a "try hard" game, like *You probably won't make it* but nope.^^ I'm a noob in platformers but I didn't think the mechanics were confusing at all and I had no problems, I finished all the levels in 3 / 4 retries max. I used a keyboard, though, I don't know if the problems you mentioned were due to the use of a joypad. I'm not sure you should make the char more agile or smaller, I suppose there is a reason behind your choice of making the char a big bunny and not the sacrificed ones, if I read that right, you thought about your character as a plush while creating it, so a bit of "sluggishness" is to be expected from that kind of thing. Usually, the saying is "the form follows the function", but sometimes, you have to do that in reverse. You have bunny, maybe you could try to work around that, modifying how he jumps, the curve of the jump, how he reacts to being stuck to a wall (maybe stick his feet flat against walls to propel himself more horizontally, for example). When you find a atypical concept, it can be great to really play around it, even more than just sticking to the "genre 101" in my opinion. Maybe putting a bit more space or slowing blades a bit down could suffice?
As for the graphics, the "arcade" art style fits really well with your game and what the character has to do.^^ So raw aspect of it pleased me, I feel like more modern platformers tend to add too much superfluous animations and it takes away from the feeling on being "in sync" with your char. The music is great, too bad you didn't want to be rated on it (I suppose it's because there are no sound effects). Interesting take on the theme. Adding the number of killed sacrificed bunnies at the end under the "thanks for playing" could make it more impactful, showing you "you made it.. by sacrificing some bunnies in the way :D".
I hope I'm not too preachy in my wording, I'm not a native speaker and sometimes my way of saying things doesn't really convey too well my tone / what I'm really trying to express. It was just my humble opinion all along.^^
Anyway, good job! I'll gladly try the new levels when they're out.
