Defender here...
Working with Kalinka on this game was an absolute pleasure.  Great guy and he managed to make a very playable end product in two weeks while dealing with a big timezone difference, a day job, personal life, and working on another game at the same time.
I appreciated the opportunity to work with all other participants as well of course, but I always looked forward to helping with this game even when it got difficult at times because I knew how flexible and communicative my team mate was, and I got to be creative again after a long time of being unsure if I could do sound design again thanks to my hearing issues.

I'm proud to have helped with this, and if Kalinka ever decides to expand it I'm definitely down!
