I enjoyed this! I think the building mechanic is fun with all of different shapes. I really like the main menu art, it was very creative. However, even after noticing the color coded attacks thanks to the comments, and 12+ attempts, the boss is very very hard, especially for a game jam haha. I love it‘s design but just making the cooldowns and attacks slower, and making the color flashes more noticeable would have helped a lot :D
Cool game! Very very good for your first game jam :D
