I just saw this demo posted elsewhere and think it looks good! The pixel are is crisp and the armored vehicles/tanks/mechs all look excellent. Weapons have good punch.
The EM Railgun feels quite a bit more powerful in both feel and gameplay than the rest of the arsenal in my honest opinion. You can be very far away for one and charging up a MAX Charge shot takes less time than consistent fire of other weapons (with the associated risk of missing obviously).
Movement felt a bit... slow(?) for the control scheme. I'm not sure what the exact adjective is but it felt a little off in some way. Maybe the boost wasn't doing enough for my taste?
Extremely promising and I hope to see more!
