Move using cursor left/right/up/down Floor tiles drop away when you step off them. Make your way to the far corner to reach the next level. To add: https://scratch.mit.edu/projects/143657513/ (level generator) WIP - NOT IMPLEMENTED YET! just exploring some ideas for a vectrex game.
xy mapping of floor coords to screen coords extracted from @Wes64's https://scratch.mit.edu/projects/41468626/ to do: have tiles drop away. draw with complete lines, no overdrawing place a character (Spike) on 'current tile' Always keep current tile in center of screen (except when animating a move from one to the next) At end of game, drop through to start tile for next game!
