Quite a hard mechanic to go through at first. Might need to have a tutorial and informational page accessible since it is a physic based game that needs a lot of time to get used to. But overall a pretty solid puzzle game to play. Kudos to you! :)
All the level design was made in the 2 hours before submitting, and I could not put the tutorial I had in mind...
I'm aware that it needs a bit too much obstination from the players in the current state, but I hope it's intriguing enough to push people to fight the frustration...
