Bit more details now that I've completed the game:
I love the story. It has a great sense of being filled with enough details and movement while still being brief and to the point. The story art (both intro and conclusion), while minimalist, is also great and really added to the atmosphere for me.
Both the Oracle running on batteries, and that fact that the janitor reveals this has 'happened before' due to them being putting them in the wrong way is hilariously keenish.
One thing that wasn't really clear to me while reading the intro story, that became clear in the ending, was what Keen meant when he said saving the council members again would help him discover what happened to Mortimer. If you do some revisions, I highly suggest making the use of the Oracle for finding Mortimer more explicit.
As I said before, I really enjoy your characterization of Keen has aloof and brief. I think it's great that the original games did so little characterization for Keen that we can have hilarious interpretations like this that 'work'.
Really enjoyed the original graphics and your usage of the Keen 4 demo graphics. They were nearly always blended in seamlessly and kept things fresh, new, and exciting. Similar to this, your blending of the various environments was really fantastic and made exploring very worthwhile. There were a number of times that I found the exit to a level and I turned back because I wasn't ready to leave yet. This almost
never happens to me when I'm playing a Keen game.
The level design was very good. While it was very linear, it did have distractions along the way and often I was unbothered by the linearity because I was so excited to move forward and see and discover the terrain ahead. You'd established in the screenshots during development that there would be a lot of blending of environments and your level design really complimented this style.
The difficulty was very good (I played on hard mode) and my only complain in this respect is that there are WAY too many guns. After the first few levels, I was never below 60 shots, and this low only because I found myself spamming shots at enemies just for fun.
The end story is great as well, although finding Mortimer alive and well and just hanging out was a bit of a surprise. While funny, thematically it felt off in the grand scheme of things.
Really, though, I'm flattered and proud to consider this as part of the unofficial TUIT story line.
Excellent work
