I just finished my first run. My first impressions are this game is super fun!
I ended up losing because I bought a generator to power my weapons, but when I placed it, nothing appeared and the card just got deleted, so I was left with not enough power.
This is a wonderful concept for a game. I'm going to play another round!
EDIT: okay this game is a banger. Once I understood how the power stuff worked, this was awesome. I did end up dying because the normal blue enemy took damage that was colored black instead of red and reached the center. Not totally sure what that was. This is wonderful and I plan to come back to play later. It would be wonderful to see how you expand on this concept!
