Hey Kami, it's about 60-80 Euro per month, pretty much enough to cover the server hosting, ssl certificates etc, plus a few beers :-)
:-D Don't worry about it Romeo. This game is clearly a hobby project, there's no goal to get insanly rich by making it. However I really appreciate the steady flow donations. That's really amazing and something I didn't expect to happen in the first place at all :-)
Still, you give us something rad, you put the effort in AND you pay for these servers so we can discuss your awesome gift to us. Least we can do is pay you back for it. =P
:-D Very much appreciated! Hope to implement some new content within the next months, but rewriting the ladder backend is really keeping me busy at the moment.
Well I'm glad it at least covers your costs. Its really a good game and the least you should not be forced to sacrifice your money and your time for it.
