I gave the game 4/5 because it's apparent the game is incomplete but has a fun core gameplay. I love the movement, visuals, sounds, main character quotes and so much more. However, due to its development stage, the game still lacks in worldbuilding (which is currently contained in mission briefings), soundtrack (which makes maps feel empty in a weird bad way that's hard for me to desrcibe), and leaves a lot to be desired outside of play (main menu ui, different gamemodes etc.) but those don't affect the core gameplay so they don't bother me as much right now. Another thing I noticed is how cluttered and/or unorganized maps can feel from time to time leading to weird and claustrophobic encounters (maps might be well designed gameplaywise but the bots pursuing the player might find themselves in tricky or unfun spots to fight). There is also so much space for various setpieces which are nowhere to be seen.
I don't want any of this criticism to come of as rude. I've played the game twice -once before and once after the last update. I've beaten all the levels using all the weapons. I loved the inclusion of flying enemies which interact with environment in a completely different way and it makes me wonder if there could be any water only enemies. I also loved the plasma gun (the one which charges up and shoots a straight line obliterating both buildings and mechs). All of the weapons are very satisfying to kill enemies with (which is always the main objective).
All in all I want to see more and I think you are steering the game in the right direction. I've shared the game to my friends and can't wait for the next update.
