Nice concept of future dominated by the swarm, although its kinda hard to parkour due to can't jump while sliding and slippery surfaces. Might be skill issue on my part though.
A good finding game. Followed game design that help to complement the mechanics such as having unique shapes for each character to easier distinguish among them.
Finding cookies is my purpose. Gunned down by Hiyori. Kidding aside it's fine. As long as you learned something, you can definitely improve especially if it is your first game jam. I'm kinda envy because you managed to submit a game tbh.
Good pixel art and music. You could put an indicator on whose player is controlling by having an arrow on the head or centering the screen to avoid confusion. Cute.
