This game is great but if the last level was really hard then i would be more interested in this game.

Nice! :)

First off, this is very clearly not a "spot the difference" puzzle game, and I'm not sure where you're getting that from.

Next, having to sit through the level intro every time I failed got old pretty quickly, and I imagine that in future iterations where the game would presumably become difficult would only exacerbate the problem.

Finally, there's really not much content here, even for a proof of concept. Five or six levels really doesn't show that you have a solid idea of where you'd want to take this. Yeah, the engine works, and is fun enough, but you surely didn't need me to tell you that.

Nice try, nice interface and physics but the fact that I managed all the levels by accident doesn't make me feel I controlled the successes. idk, maybe if we had time to position the platforms and had a start button to release the ball?

It's a nice concept, quite entertaining.
I know this is supposed to be minimalist, but still, the figures could be more eye-catching.
Worth to keep working on it, I hope there will be a longer version.
