Overall, I love the concept here and there's definitely potential for a solid full release. The detail I like most is the flying money when you get hit. It makes the damage feel impactful.
The W to accelerate in space lanes either wasn't working or lacked any visual indicator that it was working. The ship stayed in the same spot on the screen and the enemies kept coming at the same speed.
The shooting mechanic is a bit clunky. The bullets either need to be bigger or faster to make it feel satisfying. As it stands, it's more optimal to just dodge enemies than try to kill them
