Thank you very much for your generous feedback!
I would be very grateful to know where (or in which context) the game was crashing for you, since that is something the other commenters have not mentioned to date. Was it whilst editing the instruction graph or during the simulation part? If you saved your graph, I'd love to take a look at it! (The saves should be under e.g. `C:\Users\USERNAME\AppData\Roaming\Godot\app_userdata\MoonshotAttempt2`)
