Really awesome blend of genres !
I really like the survival aspect in this where you really have to be careful with your resources everytime you decide to venture further into the map, the exploration itself really feels tense as well.
Visually the ominous and at time due to some creatures and background element lovecraftian atmosphere is really nailed here and i like that there are also other mechs here and there that seem to have the same capabilities as your own where they can sprint to catch up with you if you're not careful.
The map also felt pretty huge with a lot to find and to do in it for a jam game :o
The only small issue i had was the item interaction that sometimes felt unprecise, i thought pressing F near multiple interactible objects would collect them one by one but it doesn't really seem to work that way and i didn't get why it didn't pick some stuff up sometimes.
But more a nitpick than anything cause this plays really well otherwise.
Good job :)
