This is really cool game with a clever use of the theme, but I have some feedback:
- First of all, some screenshoots would greatly increase the visibilty of your game, maybe even try doing some gifs or a trailer
- This game lacks visual and audio feedback, I never knew when I hit something and when I got hit, some particles on hitting enemies and some sound on getting hit would be great
- The pistol feels like it doesn't have any weight, some shooting animations would fix that
- Turrets have way too much accuracy, they shouldn't hit 100% of time, since this leads to quick, unfair deaths when you position yourself badly
- I could just cheese the boss by standing behind a pillar and spamming my left mouse button
Nonetheless, this is a really good game, it's definitely better than a lot of games in this jam, so keep developing games and you will become a great game dev :)
