I enjoyed it very much! The vibes are immaculate!
As others have mentioned, it's a bit cryptic, but I think it fits the retro-style and figuring things out was fun for me.
I even managed to complete the mission! Maybe I'll return one day to finish it as the other Core.
The setting reminds me of Armored Core, I wonder if it's intentional.
I have hard-locked myself, twice, on the first battle-screen. I think I got stuck in the enemy after dashing into them? I even tried turning the console on and off again, but it didn't help, so I had to restart the universe webpage. Luckily I only lost a minute.
Other than that, everything was great! Good job!
