Nice work for your first ever jam!
Pretty fun mechanic trying to decide between blasting or repositioning.
I don't know why, but it took me way too long to figure out you only really control the blue one. I think having a stronger indication like an icon on the controlled character may help. I agree with the lower comment that showing the higher healthed squares would go a long way. I thought there was something tricky about the order of movement and attacking until I read that comment.
A thumbnail and a couple screenshots/gifs helps with getting more visibility, especially for a jam this size. Even though the game files get locked during the jam, the itch page does not, so feel free to edit it while ratings are still coming in :)
Once again, good job!
