The game should pause for upgrades. Stopping to look at them and then moving to click them gets me hit every single time
Or you could make them pop up near the character sprite at half transparency with keybinds so the game wouldn't have to pause. Idk if this game is even still being worked on but I think it would be worth it
Unfortunately not working on the game anymore, just a week long project for the bullet hell jam. Thanks for the suggestion though!
