Either your Tanks Rotation isn't centered or the Camera isn't. Either Way it feels a tiny bit off when trying to turn in Spot. But it leaves Trackmarks(?) which is nice. Could be more pronounced tho.
Very nice feeling Tank handling otherwise, apart from Turning. Acceleration, and especially breaking feels nice, but Tracks should stop immediately when breaking. Not the Tank moving, just the visuals of the Track I mean.
I think it could accelerate a bit slower, it doesn't feel as heavy as it looks, but I guess those Properties are adjustable based on selected Tank and Equipment.
When stopping, reversing, rotating or otherwise starting to move slowly on slopes you slide down heavily, you should mostly stay in Place I think, a Tank is pretty heavy. Also once you reverse a tiny bit and start sliding, you can't get enough Power to move back up the Ramp until you've gone all the Way down.
"Kill yourself to end the Tutorial" is just Rude.
The stepup from the 47 to 90mm is ridiculous. Also the Tank feels incredibly light with just a 90mm Cannon on Top, it shouldn't have that giant amount of Recoil I think. Railgun feels very weak. But maybe I'm just to bad at actually hitting anything.
This needs quite a bit of Overhaul on the Maps and the Graphics, but you know that, and obviously it's not at that Stage at the Moment.
Tank should feel heavier I think, Controls work fine apart from C to freelook, as it takes away your Ability to see where you're aiming, I think I used most if not all of them and wasn't really looking for anything, but I think Controller probably plays a lot nicer then Keyboard and Mouse.
Repairing is slow and vulnerable, but I think that makes Sense, so you don't just spam it in the middle of Combat, but after a single Engagement, retreat somewhere to repair yourself in longer Missions. Would require Missions to be better structured tho, with multiple smaller Engagement instead of all just coming at once, but that's probably still to come as with the Graphical overhaul on everything. Could also use a nice Animation of your Crew hitting your Tank with Hammers or something, put that in the same Category as Graphics etc.
Overall pretty Fun, but still very much feels and looks like a Prototype, altho a rather far along one.
*Edit: Forgot to Mention the Flamethrower throws small Balls at a slow Intervall, not Flames. Reduce Damage by 10x, increase Rate of Fire by 10x, so it feels more like a Stream of Fire rather then individual Bullets.
