The dynamic music, fitting UI and low poly aesthetic certainly make this game very inviting.
This game wasn't for me. Maybe the issue is I'm too easily frustrated, but it felt like a lot of small things added up. The issues listed by PixelMetalWolf are the start of it, but what frustrated me the most was the aiming. The aiming was more to point the face than aim the gun, as based on the weapon's position on the mech, the bullets would fly to the side of the crosshair instead of towards the center by what felt like a lot. I had to put in a lot of effort just to aim the gun correctly, and due to the enemies unfair range & aim advantage, I would get demolished easily. I'm fine with the mech's low health, but resources are so tight that it feels like there is a developer intended win strat that I'm not privy to.
The music was excellent, and I really liked the look of the mechs & environment. I enjoyed it aesthetically, but couldn't get into the gameplay. I hope this doesn't come off as too harsh.
