Thank you, these are some good insights! Realizing there's a lot of things like the thruster direction and the testhall exit that I'm so acquainted with that I'm a little blind to how unclear they could be. The wiper and laser were accidentally left in the shop from a test too lol. Will probably disable grid snapping while diagonal since there's no way I know of for parts to line up properly anyway.
And I do want it to start out biasing towards "too difficult" and then let the player upgrade their starting stats/parts/starter money accordingly, but right now the upgrades system is too easy to miss or forget, being on the title menu.
