Oh, that's interesting. Someone else also had the game hang after a while. As mentioned in that comment, I'll go look through the code and give the game a proper testing itself. Will update the build id and when I find what's causing the crashing!
Also the background definitely could've been better, I agree. Initially I'd have the camera drag behind the player, but that makes the shooting feel weird so I increased the cam speed to make it snapping to the player instead.
Thank you again for playing and the feedback!
