So I saw the news for the next update and I am really excited XD also gave mea few ideas.
So first I saw the enemy that focuses on speed, so I thought, what about a heavy type of enemy, like he's really big maybe give him a shield too so the player has to try and get around the enemy to strike his back(which could be also armored to make it a bit difficult). Next is a enemy that buffs the others enemies close to it like maybe making them faster or better at blocking.
I remember you said you were gonna add weapons that will have advantages and disadvantages, I was thinking you should make all these future weapons energy based with a fairly large consumption rate so the player will always be forced to switch weapons
Lastly is most players(including myself) of the game always challenge themselves usually by things like finishing the levels without any upgrades or even clones, so having upgrades to make the game easier or your character stronger isn't really such a huge or important idea(except for unlocking weapons). I thought you should let the players spend the points for looks instead of performance. Like you should add things for making your robot/human look good for the players to spend. Maybe a color change, a pair of holographic wings, horns, sword trails, particle effects, or maybe even reconstruct a dismembered limb. They shouldn't affect the human's performance, it should be all for looks.
I mean let's admit it, we all let'd the bot cut off our arm or leg at least once, just to look like a badass gladiator who won through battles with only one arm or leg
