This is really fun, and a very creative core mechanic for this kind of game. I really like the idea of drawing shapes to create an attack, it would be fun if there were more attacks that required different shapes. The maximum length of the first attack did make it a bit difficult to use the circle attack, and it was a little picky about what actually counted as a circle. I also found it very hard to actually defeat the first few enemies and ended up taking a good amount of damage at the start, although that might have just been me being bad at the game lol.
