Not bad, not bad at all. Feels like a top down TLS.
That scream is terrifying! For people struggling to repair barricades, i'd first off recomend a choke point and keep all of the barricades behind there repaired, let them run riot on the other side and funnel into your fire, and preferably a sentry. You can strafe them all easily, too.
Leave one alive at the end, hopefully a slow one, and run him around fixing the barricades.
Ridiculous. Good concept, terrible reset mechanism. As soon as you win or lose one point from a corner, you lose another two because you reset into the middle holding the wrong direction.
It's surprisingly good for what would usually be something genuinely crappy. A small graphical update wouldn't be bad, though.
I'd also like an option to have some spells on the front bit of attacks for mages.
