Having fun is the best part! I had a blast making my game and learned a whole bunch at the same time. I think your game is definitely a functional prototype and could be expanded upon for sure if you wanted to continue with the concept. Maybe make the scavenging more of a skill based minigame instead of a take it/leave it or fight/run choice? I dunno. I still had fun playing yours though. Something about watching the tiles rise and fall as you glide your mouse across them is so satisfying!
