I wanted to try out different techniques and tried to replicate the "experience" of the Game of the last log. I got away with a 320x320 pixel tile. The drawBitmap function of the display library seems to do something right :) so no tile engine seems to be needed, but I'm interested to see how @Radomir Dopieralski is doing it over at https://hackaday.io/project/27629-game/log/69791-inside-a-tile-engine
