pretty good i was surprised by the steam punk ship. its somewhat fun the money should be called points because it does nothing and it had good sound effects and the fact that it has boses and power ups is pretty cool for a scratch game. it does need a bit of oomph or game juice if you have no clue about this mark brown a youtuber made a video on the topic

Shots pierce through multiple enemies when firing towards the left, but not towards the right. That's the sort of thing that should be noticed in about 10 seconds of bothering to playtest your own game.
