The main character is 14 pixels rather than the full size 16 to workaround the bug/phenomena mentioned in [Maze tile map navigation issues](https://forum.makecode.com/t/maze-tile-map-navigation-issues/484). Is that the issue you encountered? The good news is it’s being worked on. There’s also some _undesirable_ wall collisions for the enemies so we’ve had to destroy them when that occurs as a workaround for now. The Meowbit is a bit of a puzzle as well as a challenge with the d-pad. Level 2 works on it but the very similar level 3 gives the dreaded `021`. I don’t know if that’s an issue with us not cleaning up objects or some sort of fragmentation / lack of contiguous space issue. I’d be interested in any optimisation techniques for the white dot sprites as they don’t need most of the normal sprite functionality. I did a prototype which got mostly discarded that had “can i see the player” functionality in pure blocks. That was implemented by firing black pixels as fast projectiles continuously in four directions and sensing collisions - I was proud of that hack! --- _[View the full topic](https://forum.makecode.com/t/presenting-chomper/493)._
