Love the game, it's a lot of fun trying to decide between levelling up the towers like normal Tetris or by leaving an empty spot. Graphics look great too. Not sure how to defend against the pink ones that fly right through the towers though...
Thank you so much for playing! And yeah the "bomber" enemy ended up a little bit unbalanced, between adding them and the 2x2 tower and fixing major bugs in the process on the final day I didn't have enough time to tweak it to the best. Glad you enjoyed!
