Hey I played your game Snowball! It was actually a pretty cool concept! I know it's just a demo but you don't have to listen to me. You should add HP bar to the player and a HP bar for the car. Cause right now when I was playing, I was pretty much on god mode and the snowmans did not aim for the car at all. You should add more spawns for the snowmans, 3 is not enough in my opinion, maybe have like continuous spawning? Also where the lake or whatever it is, the snowman's could not get down their, maybe make a platform where they can come down? Once again I enjoyed playing it for a good 10 minutes, good luck to your future updates on this game! Hope you don't mind I made a video on it! :)
Skip to 7:10 for my perspective if you want.
