I think game is great and i like very much.But...
There is no option to restart.So if you frick up on early minutes you need to kill you robots or just die slowly to restart.Also i found a bug(?).On level 3, after starting, some of my workers died and i open menu to check if i can restart(was playing for first time) and, after closing it, i stop getting resourses to body parts.So i was needed to restart whole game again.
Overall good game for this short period.Nice graphics,sound,music and story funny too.
Good idea will be maybe add some form of actual threat,like spiders or something,so you need manage them too.
Have a nice day,hope this helps.
