nice , but got boring real quick
i love everything, the art, gameplay,hud
the only downside is, it got boring real fast if theres no other accomplishment/boss/even a mini boss / a simple story from each /every 2 wave might not make it so boring anymore.
the fast paced make it more strain on the person, its like playing game on infinite mode.
shortcut for pause and changing weapon will make it more interesting , the space bar could be used for pause rather than look for how much kill&money :p.
just a little fix here and there, its perfect ^^
i found something funny, if you target your back, it looks like hes doing yoga ^^
