Thank you so much for the amazing feedback! And congratulations on being probably the person who went the furthest, at least from what I heard.
Your feedback is really great, especially the balance feedback because I didn't get a lot of time to balance the game, and it's really helpful to get feedback on the last tier of guns, since I didn't test those as much as I would have liked.
Pausing the timer when the shop is open makes a lot of sense I think, that's a really good idea, and adding chests is absolutely on my todo list.
Really happy you liked the game, and thanks again for the great feedback and the time you spent writing this!
