Well done on your first game jam! I really enjoy the movement and attack scaling, the only note I have about it is the strictness of the punch as a hitbox makes it incredibly hard to hit the flying bugs consistently. I think your level design could use a bit of work, the platform with three enemies (which is already incredibly hard to make it onto), is followed by a jump that is extremely easy to clip your head on and die. Being that late in the level, I spent about 10 minutes in that room alone having to grind back all the shards in order to attempt the jump again several times over. Take all of that with a grain of salt, I had a lot of fun playing the game (and honestly had a lot of fun with the floaty jump itself) and you should be extremely proud of the game you put together.
