This game is exactly what i was looking for:
a dense atmosphere in a very threatening environment.
I think it builds up a healthy amount of pressure for you to make every decision count. Since there is not much space for mistakes you can easily run into problems, but i rarely had the feeling that those problems were not solvable. Its even fun to rewind a bit and rethink your build. Nonetheless im aware that Ixion is probably not for everybody, because it can be stressful (and thrilling).
I Finished this game twice and i wish there was more content and replayability to it.
Also noticed some bugs, that will keep you from getting some achievements, which is the only real annoying part of it, since it can take forever to play to a part where you can try to get it again.
