Awesome that you included in-mech and out-of-mech combat. I will say fighting the enemies felt a little pointless and repetitive, I kinda just speedran the whole thing after the first few enemies. I also found you can cheese movement by blocking in the air, your stamina regenerates, and you can keep jumping/flying by doing it over and over. If you get out of the mech it flies off really far and at one point I thought it was a bug and my mech despawned, so I think it could use an indicator to point to where your mech is. I'm sure you could accidentally send it to a location thats inaccessible so it might need some kind of recall function.
Anyway the greek mech vibe was really cool, love the spartan warrior / tallgeese vibes on the main guy. Nice work!
