Cool game! Cool art, and overall easy to play! I thinks some kind of difficulty progression would be nice, played around 20 minutes and the game felt like it did not get harder to me over time, so it gets a bit boring. Raising the difficulty over time could help this. I also found that I nearly never moved around, and mostly switched between shield and gun. So some kind of reason to use the movement module more would probably a great addition, as it is already implemented ;D But otherwise a nice, chill game!
