The critical path for the first visit through State-4 is almost complete, a few rooms remain, followed by the fight against Ensign E, but then you'll move on. I've tweaked the way guns fire - and I've added a new gun that shoots blobs of acid at an arc - and I've added a few more rooms. Everything is going smoothly!
Time spent on the project so far: 394 hours
Currently working on: Moving on with the story
