I just started a small game in Unity2d that uses my customized mesh renderer to draw a map with a tileset. The object of the game is to move a propeller that constantly rotates through the map without touching walls (simmilar to Kuru Kuru Kururin for the Gameboy Advance). I'm not too good with pixel art but all I need is some simple tiles. Something like the Kuru Kururin tiles will be awesome. I started some tiles but they look bad in my tile editor. Attached are some of the tiles I created and a sample of Kuru Kuru Kururin tiles.
