Your damn right we need more fast mech action, and by game that's here and the influences your wearing on your sleeve you have the right idea of how to accomplish it. The momentum of the player, specifically whenever boosting is involved, is a little weird, but since it looks like it couldn't have been a month or two since development started, you're probably aware.
Also, selecting the heavy mech, game over'ing, and then selecting the light mech removes the missile launcher of the light mech. Keep it up.
