Thank you for the feedback, I'm glad you liked it.
I am terrible at art of any kind, 2D or 3D. I did not know how to make it look good so it ended up like that :(. I tried playing with light a bit, but could not get much better and was running out of time.
Enemies spawning in large quantities is actually trying to cover up the fact that they...erm...suck :). Also, it gives player the opportunity to really flex TK. Combined with the fact that enemies die at the slightest touch of a body or box, you can really mop the floor with them by grabbing bodies and tossing them into groups.
But I do agree, better balancing and fixing some of the bugs would have made it a much better experience and wouldn't need to abuse the spawn rates.
