Cool game, I love how you made onboarding for the game (explanation)
Game has nice peace clear goal and pretty funny and unique story.
Puting gun from parts is cool mechanic, but event we had some schema I could just spam left click to finally lucky find the right spot, probably there could be place to somehow punish player for wrong way of building a weapon. Maybe just allow to put it on different spot but that could cause that weapon need to be unfolded to put again?
What I would improve is generator mechanic I was able to pump it up when I was hide behind doors that mede game pretty easy. There is potential to put it away from hiding spots
Good job and congratulations on your submission
