Interesting wave based game here. I really like the concept. The balance between trying to dodge the enemies while also controlling the umbra added a cool mechanic to the game where you had to manage 2 things at once.
I did feel like the umbra felt a bit off, almost like it was not going to where I wanted it to go. The movement for the umbra was also left click for me not right click. I also think you get too much health, as it felt it was a bit too easy. Maybe you current health carries over between stages or you just get less health overall.
Awesome job with this submission!
