This game is absolutly incredible ! I haven't had this much fun in while. I do have some things to say though :
Enemy missles feel nearly impossible to dodge. Maybe add some sort of counter measures ?
Helicopters feel like the strongest enemy so far. They appear unphased by smokes (i love smokes, the most usefull and neat thing to use in the game imo), i cant seem to hit them with any missiles, they feel like they have the most health out of any enemy in the game and they do so much damage and fill up your screen very fast. My suggestion would be to make a heavy mech which has the same damage and maybe just a little more health then the helis while lowering the heli HP and making them vulnerable to smokes.
Now some things that I would love to see :
Battles where you have allied units attacking a hostile stronghold with you.
More mechs and boss battles (Pleaseeeeeee)
Infantry that could take cover in buildings and launch RPGs as well as peper you with machine gun fire
The health bar being out of 10 can be very confusing, sometimes you take hits and it looks like you dont take damage and sometimes it feels like you get hit once and lose 3 HP. Maybe making it out of a 100 or 100% would make this better ?
Different cores (which would give you an an amount of power/wheight ratio allowing for faster, smaller mechs and larger, tankier mechs), engines (tradeoffs between cruise speed and overdrive) and armors (again tradeoff between wheight/protection to different weapons, maybe even allowed an Active protection system to intercept missiles !) sort of how armored core 6 works.
Two different weapons systems at once (one of each arm) : as an exemple you could be able to pick duel gattling guns, auto cannon + railgun and things like that. I think it would really open up your options and how you fight against enemies.
I'll be following this game cause i cannot wait to see how you make it better !
PS: pls make a discord i have more good things to say about this amazing game
