Nice game! Took me a while to find the coin, but felt good when I did!
How I would change it a bit: give the triangles some pathfinding so they don't get stuck in walls and make them invincible or give them a lot more HP. This way, they're scary and you're forced to run when there's many of them, which should slowly build up an army following you and at the moment you find the coin you just stop running and blast at them till you die!!

Thank you! I think I'll implement the enemy health idea if I decide to update the game in the future, that would definitely make it more challenging. I probably won't make them invincible though, sense they have a small chance of dropping the coin, but nonetheless, thanks for the feedback as it is greatly appreciated!
