This game is just what I was looking for as a mecha fighting game, real awesome pixel art, I still have the old demo, looking foward to future updates.
As sugestions, would be interesting to see more technological stuff added, like hard-kill APS defense systems (literally a bulet like projectile that strike an incoming misile) and soft-kill defense (like an automatic smoke screen when target by a enemy laser rangefinder). Technologies found on current tanks and misile lauchers, as real world inspirations.
Also would be interesting some level of customization of the mecha, an option of a more tank like mecha, with caterpillars maybe (an interesting visuals are the Object 279 and IS-7 tanks). Regarding main weapons a cannon similar to the ones found on current main battle tanks, 120, 130 or 140 mm rounds, for example.
Features like the ability to give small bursts, increasing the velocity of the mecha for a short period of time, release flares to damage small targets, or detonate incoming fire (like in fighter jets). In addition of the main weapon and the possibility to launch missiles, would be nice to have an light weapon, like a small machine gun. Another think nice to have in the mecha, now thinking on a new kind of enemies, would be an automatic anti-air gun.
Great game! Hope that the project keep alive, looking forward to support it. Wish that my suggestions may helped, or have given good ideas for the game's development.
Keep the great work!
