A nice easy-to-learn mechanic with logical complications. Also, really enjoyed the music while playing!

Hey great concept! I enjoyed it quite a bit.

I like the music! I must admit I pressed buttons randomly in order to get through level 12 - I’m not sure what the function of the coral blocks is. Either way, nice game!

It took me a while, although I mostly brute-forced my way to the end without planning my moves too much!  I always have a soft spot for puzzle games.  It was a fun game with a nice cozy soundtrack.  Great job!  

Ran the Ubuntu 22.04 without an issue. Made it to the last level but could not figure out the hidden combo

If you can't run the game on linux from binaries you can run windows version with wine:

wine start /d waller/bin waller/bin/waller.exe
wine start /d waller/bin waller/bin/waller-editor.exe <level-number>
wine start /d waller/bin waller/bin/waller-editor.exe -W <new-width> -H <new-height> <new-level-number>

This seems to (unfortunately) hang after closing the window, you will need kill the process / interrupt it with ctrl+c

Hey. Haven’t been able to run from binaries (on Gentoo nor Ubuntu 22.04 VM), but easily started from REPL, thanks for detailed setup instructions, fellow Common Lisper :)

The game itself is veary relaxing and enjoyable. Wasn’t quite sure about all the rules, so failed to solve 9, 11 and 12, but still love it :)
