Using time as a health bar is really creative! At first when I got hit, I thought my character’s HP would keep draining. It wasn’t until my second run that I figured out it’s just the timer ticking down. I made it to level three, but I ran out of time soon after. New levels don’t give you extra time, so any mistakes you made earlier keep haunting you as you go further. The game basically turns into memorizing every level and rushing through as fast as you can. Overall, for your first game, it’s really well done. Keep it up!
