:) I made it to 275! The game has decent polish in interactions and sound fx. The core gameplay loop is there. I can easily see this on retro-focused game consoles.
Constructive Improvements:
-Add variation to the gameplay over time. After reaching 50 points, or 100 points or 200 then 300---how does the gameplay change or grow more interesting? New map? New powerup? New enemy? New Life or bonus round? Right now there's no real gameplay change for lasting over time and doing good.
-Refine the art. Right now you have the retro 8-bit visual but you can still fit details into the pixel art. Details on the diff carrots, details on the diff trucks, maybe even weather. Definitely experiment with environmental art or even levels so at least the scenery or theme can change. Different farms perhaps? Collect potatoes on next round?
-Keep the sound effects you have. It works for the gameplay loop. Fairly fun for a 12-hour game. Based on that you refine a core gameplay loop in such a short time. Good job.
