[I share my rating publicly, because i feel like that's more fair for you and me]
Gameplay: 3 stars → The gameplay loop is really well done, but after buying the upgrades there's no goal and playing feels pointless.
Theme: 4 stars → It's really a good idea, and it works really well. I just think that good players would have no reason to spend their money
Polish: 2 stars → little things like the bottle breaking particle or the "-2$" are good, but I don't think the look really great, but at least there are some
Visuals & Audio: 2 stars → I love the pixel art, but it could use some y sorting and shadows. Also since it's not pixel perfect, the movements look out of place. The audio is not balanced, I'm sure you noticed it but the shooting and bottle breaking sfx are very loud. Also i believe the font is not scaled properly (it needs to be scaled by a factor or its original size). In my opinion a talking sfx for the npc would make them feel much more alive and add immersion.
I hope this isn't too harsh, that's not the goal
