The music is addicting, incredible job! The gameplay is so incredibly smooth, I love when a factory game is well made like this! My only remorse is that there is no way to find out what a piece I already unlocked does, maybe an explanation on hover would have been cool. Unfortunatly, I encountered a bug that stopped me from rotating any piece. Nonetheless, I still LOVED this game (while it lasted lol) and I can't wait to see more games from you.
