Ok took a bit of luck to see the shop and then everything made sense and the game was great. Unfortunately the second time I opened the shop it gliched or something and I couldn't select anything. The game has very good mechanics which I'm surprised you had time to add, so hat's off to you! The breathing mechanic with the screen effect, shop, weapon variation and enemy variation, sprinting (awesome running animation by the way. very nice!). Sometimes enemies spawn right on top of you which is jarring, but I think I might be able to beat it if it doesn't glich, so looking forward for a 2.0 version!
