Really fun gameplay slice for a cool concept !
I really like what you did for picking up and dropping packages, having this just be on a simple click for each arm is super intuitive and makes it a quick action tu pull off. The mech has tight controls with just a tiny bit of jank sometimes, mostly you can get a bit disoriented cause there's no real refferential for where your legs are facing relative to your view, cause the little bar on top shows only the view, but that's really the only issue i've had.
The artstyle is amazing and i think the corny 50's ish sci fi look complements the humoristic tone very well. Voicework is also really good, and i laughed quite a lot at the little 4th wall break for the jam version :p
Cool that you still allow players to have fun and try out some more deliveries past that as well.
Game has quite a bit of polish already for a jam game, good job to you all :)
