My feedback is already somewhere down there, but there is gameplay if you wanna see it: 

The control is nice and smooth, but once I get both characters to touch the door, nothing happened.

maybe you need a tutorial pop ups.

I don't know what I'm even supposed to do. Nothing happens when both characters touch the door.

Could nto pass trow first level, i press spacebar but noithing happend. Do i need tro touch all clouds or something?

I don't know how to get to the other levels or what the goal is.

Looking forward for complete game. And its a browser protection feature that causing it to not start.

There is no goal in the game.... And I found a bug when the other player touches green player, the green player will teleport

I love that you can stand on top of the other character. Nice peaceful vibe to the art style, too

Great attempt! Feel free to review my game!

not really fun, not completed, & no real clear goal.

i can see that the game can be completed, its just not really ready

if you want too, check my game, it can really helps a lot :D

I couldn't pass the first level, which was strange. The art style was nice, though.

Nice art style but could not pass the first level

I feel the game is not finished yet, huh?  But hey, continue on gamejam journey, ut's fun!
