For what the game is, it is quite well done. But I think you could have been more ambitious. Even if you wanted to keep the core gameplay the same, adding menus, a leaderboard, or cosmetic options all could have been good expansions.
Unfortunately the time it took to get the basically infinite amount of bugs fixed didn't leave enough time for polish, lol. I agree with you though, its probably on me that this game isnt as polished.
