Fun concept and idea. The movement is fun, but I wish the screen was either wrapped or that I had a bigger play area, so I could really get to enjoy shooting and moving.
As a prototype it’s great, but going forward I would add more risk/reward in. Maybe make two firing options, one that kills the enemies and is an easier shot to land, but doesn’t give health and then one that doesn’t kill them, but drains health and is harder to land … like a beam that only goes out so far from the ship or something.
Enemies that were threatening would be good too, but I’m sure you know all that. As a concept, you’ve got a great base here and I can’t wait to see what you do next round! Good work. I played on stream if you want to see in-the-moment feedback.
