The servers should be joinable, sometimes there is a bug involving Steam Networking and bots which prevent this from happening rarely. I'm looking into a fix, but you should be able to connect directly to the server IP in this case.
I'm sorry that you're facing difficulties. Typically, this is when there is an older version of the SDK installed for another mod, make sure you are on the pre-release branch of the SDK.
Thanks for the feedback! I'm glad it was enjoyable. And yeah, I was a bit too harsh with the enemies, and did not tutorialize the movement mechanics enough, so it just ended up being frustrating. If I had more time I would have definitely liked to adjust the movement speeds more to get a perfect balance.
I'm definitely going to continue working on this game, the amount of bugs and optimization issues bother me, and my mind just continuously nags me to fix them.
As for the lighting, I realize it is too dark. As said before, the game was supposed to be completely different, so when I changed it to be maze based, I didn't have enough time to optimize lighting, and many, many other things for the new game features.
Well, I was making a better procedurally generated map with actual rooms and stuff, but I realized I was running out of time, and had to use simple maze generation code. Generating mazes is pretty simple stuff.
