Thank you so much for taking the time to play, screenshot and give feedback to my game.
I really like your idea, I wish I had thought of that. I could make better-designed blocks with lights on them like the long bock, and they could flash when you get a 3D tetris.
This is a jam game and I have run out of time and energy. So I have cobbled together a speed tower-building game. But I defiantly want to start again and follow your idea since I have already done all the hard programming work.
