Very enjoyable! I haven't played any of the games cited as influence for this one, but if they're anything like Infested, I need to play them! I loved all the ways you can die (and of course, the fact that the game auto-saves just before your fatal mistake, thereby avoiding unnecessary frustration).
Thanks for making this great game free. I'll tell my friends about it.
By the way, I ended the game with several items in my inventory that I never used. Did I miss some secrets? Were they planned for sections that were cut from the final game? Or are they just there for flavour?
