Very original concept. The music was ok but not amazingly good. The art was pretty good. Especially the robot and the background. Too bad the background didn't move, although that might've been your intention. It's hard to say what you did wrong as you might've put it in the game on purpose. The portal could've been better I think. The gravity could've been a bit better so it feels more smooth to jump. And UI could've been more polished. with that being said though, there were over 15 000 sign ups and about 5000 entries. So you did better than 10 000 people already. I think the game is fun to play for a few minutes, but I don't see much potential beyond that. And that's perfectly fine for a game jam submission. Good work and fun little game!
