Monster Mind was written in HaxeFlixel which is cross-platform, so while it was still a lot of work to port it -- I did not really have to rewrite the game from scratch
Brick Break was unfortunately written in ActionScript which only compiles to Flash, so I will have to rewrite the game.
It IS still possible -- Brick Break was a much smaller game, so it only took me about four weeks to make. Even if I rewrote it from scratch, I should be able to make it in less than four weeks! I don't have to draw or code anything. Maybe some day!
If anybody is interested in picking up the reins or learning Unity or Godot or whatever, and wants a personal project -- I can give them the source code and assets for Brick Break and they can take a crack at converting it themselves 😀
