Thank you for your feedback ! For the game jam I wanted the game to be only one hand playable so the shop is not clickable but I'll fix it after the Jam. And yes the shop is up every 30 second, I'll think about giving a feedback for the shop comming up.
Thank you for your feedback ! Yes I saw that when the enemies are swarming the shake is a bit hard.. I didn’t found yet the correct fix to keep a good feedback without it being annoying when you’re in the late game.
