This is a really well polished and complete feeling game, actually had a lot of fun with it. I never got attacked or took any damage, I don’t think that was intentional, but was otherwise just so amazing. The visual effects, the game feel, the dopamine and satisfaction whenever you pulled that lever and the numbers just go up (or down, for the enemy health :)).
I also really loved how the “play” button was baked into the gameplay like that. Very cute, very clever. Well done!
My only wish was an audio slider or settings menu somewhere. Maybe there was an I missed it.
