I actually went back and played the last version to check the differences in detail.
This new control scheme is much more immediate to grasp and the third person camera is good too, it helps orienting the mech like you want to while keeping an eye on terrain.
The automatic ground mode is not reliable, sometimes you take damage trying to land and sometimes the mech switched to ground mode mid-air.
You are trying to nail down movement and controls so enemies should really not be this tanky and deadly. I suspect part of that tankiness is because the aimer isn't perfect and the autocannon doesn't have much AoE.
As the game works right now there's 3 possible way to engage enemies.
First is form the ground: this doesn't work for obvious reasons, but I can see it being viable with some cover and as a way to safely destroy AA missile launchers or something like that
Second is strafing the target as a plane: this also doesn't work well because the autocannon is inaccurate, but the movement to achieve this is present so it's possible.
Third is while hovering and knowing mechs, this should be the game's strongpoint: zoom in, start hovering, unload your gun, zoom out if there's any danger. But this also does not work. Hover mode takes forever to kill horizonal movement even when you're orienting the mech so that the engine is pointing towards your previous direction (which you don't want to be doing too much if there's targets to aim at)
Then, when you need to get going it takes forever to accelerate away from danger
Hover mode is THE way for players to reorient their vehicles without needing to do a wide circle in flight mode, but this breaks massively at high speeds as it takes you way too long to decelerate.
If you want this game to be the mech equivalent of a flight simulator then I guess it would make sense to force the player to learn the vehicle's limits and keep the speed low before attempting an hover drive-by, but if you want to make something more arcady it doesn't make sense to punish the player for going as fast as possible.
Minor bug: the autocannon ammo count starts as "text blo"
I'm looking forward to see where you take the game from here.
