Cool game. Surprisingly well polished for only a 2-day project. I wish I could not over scope my game for once :D
The moment when I realized for the first time that in the reverse world, you push the goal instead of the box gave me a little smile :)
I feel like the rules of the apples are not communicated well. It was good enough, I eventually got through the level but there was a hiccup. I quickly got the idea, that in the reverse world, you don't want to touch the apples but the game didn't tell me anything about destroying the apples. I got the idea only after eating all the red apples and the game not ending. Also, that was the first level I saw that the spikes can be pushed in the reverse world. Wouldn't be better to teach that separately at its own level?
