I admit I struggled a lot with the mechanics but that's maybe just me being bad at fighting games ahah. Congratulations on this amazing submission though! The art is phenomenal and so unique even though it's not my type, it's great! I really enjoyed the game a lot, it was challenging but a good type of challenging and not frustrating. I found myself learning things during gameplay and getting used to mechanics which triggered some "Aaaah I get it" moments that I really enjoy. However, this can also be due to some lack of required explanation sometimes. For example the health is supposed to be the post-its on the corner (which is reaaaaly creative) buuuut it should be clearer (I only noticed that was my health in the middle of my playthrough ahah).
Anyways, really fun game, the fighting mechanics are enjoyable even though they could use a little bit more work: attacking could have combos like attacking multiple times or combining attacks (this is a 4 day gamejam so it's just a suggestion for later). The blocking is satisfying, however, it's only satisfying when you get the explosion upgrade. The normal block lacks some kind of feedback that would make it more enjoyable in my opinion (maybe a camera shake or slowmotion effect or an SFX).
Overall I had fun, even though this is not quite my type of game, you managed to get me in the flow which is really great! Congratulations once again for the awesome submission!
I would appreciate if you could rate my game as well and leave some feedback! Hope you enjoy it!
