It looks very polished and it's very fun, but challenging XD After being stuck at wave 4 and getting an upgraded weapon I managed to beat it ^^ Also took me a while to figure out how to "open" chests.
Congrats on beating it! I’m glad you enjoyed it and that it wasn’t too frustrating :D Initially, you could open the chests by interacting with them by pressing E, but we wanted to add a bit more chaos, so we figured the game could always use a few more bullets.
