This game is great but gameplay is limited. I like the wall running mechanic as well as how the enemy's limbs blink when it's weak. But this game needs some more game modes. Here's some suggestions:
1. Horde Mode (Already implemented)
2. RP Mode (Nice to get a a little background story and because it looks like this mode could come out pretty interesting)
3. Fortress Siege (Raiding the robot factories)
4. The Maze Mode (The player fights to get to the middle to where the boss defends a prize)
Please consider adding any of these and I think it would greatly improve your game 👍
