Push Puzzler by STF (Released in 2021) is a neat sliding puzzle type game in which you need to solve the puzzle in as few pushes as possible.

The neat thing about this game is that it's written purely in BASIC 2.0 and isn't protected, so you can view the code and possibly find some tips or tricks to use in your own code.
