Try to give yourself some slack. I too enjoy those games and have a toddler and an interesting side project. What works for me is to let myself unwind with some game time. And similarly reframe any time put into the side project as a win, even just a few minutes.

While I do get a rush from being productive it can be exhausting to always be 'on'. Games are one way to turn 'off', bring some variety to life, and experiment without guilt. Just remember that you don't have to finish the game or win every match.
