A couple things:
- There are some files missing from the assets folder, notable Title.png (it is called title.png instead), boss.png, and playerdead.png. The game crashes when any of these pictures is needed.
- The text at the beginning of the game seems like it's supposed to go at the end. Then again, it wasn't very informative anyway. It might work better to explain to the player what's going on, unless you are going for a 'just throw them in' feel, in which case you might want to take it out completely.
- It's only because of my history as a Linux user that I knew how to install pygame and get this to work. As another user suggested, you should legitimately build you game before shipping it. I'd trade in-game quality for out-of-game quality any day.
- The false options menu was clever, but the red block text killed the mood (I took a mood star away for that).
- As another user said, the spacebar mechanic was frustrating. You should give the user a fighting chance, and maybe punish them for button-mashing to make sure they don't cheat.
- The controls for starting a new game and continuing through the levels were inconsistent. And please, ditch the "X out to continue" thing.
Things I did like:
- The art, although simple, was neat. It gave the game a kind of mystic, story-telling feel that detailed minutia just can't deliver.
- The audio was awesome; the fact that it just played continuously through the hallway and the encounters made it feel like there were actual smooth graphical transitions (which I would have appreciated).
- On that note, the font on the title was pretty great too.
TL;DR: Cool game, love the mood. Needs a better play mechanic and some polishing, though.
