Well...
I like mechs. I like heavily armed mechs. I like blowing things up with heavily armed mechs.
There were a few glitches I noticed, such as movement problem where my mech would continue walking over a ledge while I was trying to go elsewhere. Also one of the shops didn't work when I came back to it.
This of course reminds me a lot of the old school Smash TV game for Super Nintendo. The biggest problem I found with this game was that ALL the enemies shoot at you unerringly, and immediately collapse on your position, destroying you quickly at point blank range. If some were melee attackers, or AoE self-destructors, I think as a player you'd get more enjoyment and challenge out of utilizing the obstacles in the rooms, which I'm sure is the whole point. Currently in level two, a room has 10-15 mobile shooters, 4-6 static shooters, and a circling shooting leader (or three). You disappear quickly in the hail of incoming bullets and lasers. No fun at all.
Failing that, some in-fight power ups would spice it up, shields, nukes, AI helpers...something!
I didn't invest more than half an hour in this game, unlike some other unfortunate players it would seem. Perhaps I didn't get to see some of the advanced content, but I doubt it.
