Very atmospheric, I'm eager to see the rest of the Phase series. Eerie, yet pleasant, and thoroughly mechanical without overdoing it with cogs and machinery, you've done a very beautiful job with the world you created for this short. It runs more like a presentation reel than any sort of prologue/story though, so just watch out for that for the next installment.

There are issues with how laggy it is and the occasional teammate getting stuck against a barrel, but concerning concept this is definitely a game I can get behind, especially the arena mode.
It has the timeless Madness feel combined with easy-to-understand gameplay that surprisingly doesn't get boring- in fact, it's pretty addicting and despite the bugs and lag, I keep coming back to play on arena mode.

Maybe in the future, after the lag has been fixed, you could add some more hats, glasses, a.k.a. customization. Also, the scars/bandages look very odd over headgear.

In the end, awesome game, I can't wait to play the less buggy version, especially since you guys are planning to implement high score boards. Cheers.
