Really cool idea and art style! I think that the enemies weren't threatening enough, I could just line up the boxes in the two middle columns and easily win without having to shoot or use the shop. Also I feel like sometimes my movement inputs didn't register when trying to move one tile at a time (maybe there is no buffering and I was pressing during the previous move?). I won't take this into account when rating since I was using Wine/Linux and it could be on my end. Nice to see that you plan on continuing to work on this game!
