Yo! Nice game, I played through a few of the levels. This really good for your first game.
EDIT:
Okay, I got to one level and got stuck, its pretty hard. But that's good makes us think. One thing I think you could add is a way to regain reveals. Like maybe a pickup that player can grab but make the level harder on the side where the pickup is. Just a small thing that could be added in the future. Overall 8/10!
