For a tech demo, this was really neat! The mechs were neat to operate, and everything animated pretty well. It was simple, but very pleasant!
If anyone wants to make this a bit more interesting, I recommend trying to get either a 1 or 2 legged mech to the final level of the game, it makes you have to use all of the tools the game gives you.
I had a lovely time playing this, and I hope what you made here goes somewhere someday!
