Cool entry!

I think the concept is interesting and with more work could turn into something really unique. I like the fact that you can customize your mech (although I wasn't able to use the build screen to do so), because it makes me think that you could have different abilities show up depending on what parts you have equipped.

I feel like the game could benefit a lot from more work on the game feel side of things. For example, when you attack, the animation where the mech cocks back the arm is cool, but then the swing doesn't feel too powerful, and the sound effect you chose for the punch sounds a bit too light, like you're hitting a small metal object. If you can sell the player on the size and weight of the mechs through those things, I think you could have a much more satisfying game feel all around! 

I think you could achieve a lot of interesting things in terms of mechanics. At the moment, I don't think there's ever any reason to defend because the enemy mech seems to always go for attack. I tried defending when I thought their special would come online, but they just punched me anyway, and never used special in the fight. However, this made me think that if you maybe made a few more mechanics, and tweaked the AI for the enemy, you could achieve a very cool sense of strategy in which you are trying to figure out what your opponent is doing to counter it.

I hope you keep working on this, keep up the good work! :)
