Great game! The lightning feels amazing, the sound, screen shake, and color changes are all fantastic. Simple and very juicy. I only managed to survive up to wave 6 after a few attempts.
I do have some points about the design that I didn’t fully understand. For example, for most of the game you stay in shock form because you need to constantly defend, especially against the faster enemies later on. Because of that, I didn’t really see the usefulness of upgrading dash and heal, which, if I’m not mistaken, only work when you’re near the tower and in human form. When I tried that strategy early on, I got destroyed. The same goes for the magnetic ability, it feels better to kill enemies close to the tower, especially since you get teleported back to it when you switch forms
Overall, great job, the game turned out really fun!
