Nice job finishing another mod. From what I've played so far, I liked the sound effects and the planet pictures next to the machines. I was quite disappointed by the lack of new enemies, though; it would have been neat to see some other than the standard Keen 2 ones. I was also disappointed that many of the tiles were just reused from the originals. That said, what you've done is nice, but it feels somewhat incomplete, almost like a demo.
I'm sorry if I came off sounding rude, I was merely saying it seemed slightly unfinished. I can tell you've put a fair amount of work into it, and I quite enjoy the level design and graphics that you did from scratch. And by "demo," I only meant that I hope you continue with what you have here, since it's a great starting point.
He made them intending them to be full mods, before jokingly saying, "sure, it's a demo" after some person was disappointed with the lack of new enemies. But then I played along and he thought that people might actually think that it was a demo, so he stepped in and said that no, it was the full game.
