So, I was mashing the fire button and suddenly the level ended. Since I was still mashing, I accidentally bought something in the store. Besides that, the crosshair feels snappy and responsive. Nice entry, congrats!
Thankyou for your reply. I will be adding a confirmation pop up for the items on the post jam game. On the level end issue, I will also try adding a buffer for button mashing between levels so sudden level ends dont occur.
