Really cool entry and i like the looting / inventory system.
Although it is a bit confusing at first cause i wasn't quite sure how to equip stuff and i didn't even notice the tiny icon to indicate you could loot enemy mechs. But once you get the hang of it you can really feel the upgrades, do quick repair to have a more decent hp pool, especially when you loot some armor.
So aside from the small confusion at the start, it's pretty solid and fun, just too bad there are no sound fx to complement the package but the music is very good, and i really like the low poly mechs, and also the overall design language / visual cohesiveness which ties this one to your previous entry's universe (at least that's how i saw it ^^)
Overall good job :)
