I DID go through it as much as I could: got the jetpack, polar star with the limited ammo, mimiga mask?, stopwatch... fought the ... Critter and the Bat. Fell to my doom, and also kept going back to Cthulhu... but he always said... come back when you've done everything. What Is Left?! The only path I haven't explored on the map was the unreachable part connected to the top. Anyway, interesting mod concept, but it had a bunch of things working against it.
Such as: If the almost black paths are supposed to be barely visible, you should probably make it a bit more visible still. I had to adjust my display in order to see the paths ...
No music, or interesting use of the silent environment...
The mod would send me back to a true New Game if I died normally to anything. Like spikes.
It was too aimless. Once you reached the last room, it sends you to the title. And even when finding the "The End" room, I don't know if it's over since there is a NO, and the Cthulhu telling me there is more to... find.
What were the items for? A Clock... a mask... etc... I was waiting for the big reveal, but never found anything. And running out of bullets seems odd and possibly a game breaker. Also, ignoring a boss and leaving the room causes the boss music to play forever. Lastly, one chest had an unusual message, empty with a question mark? Why were they different?
Anyway, it seems creative... but it needs Something... imo. You have the maze, but no cheese to find. It does make a good psych project though, how far is the player willing to explore with no direction? What makes them quit? When they find The End, do they ignore it and seek "NO". I'm reaching here, but anyway... glad to see a creative entry!
I bet this would be more fun with some friends; to tease them to try to find everything, maybe with some hints. Reminds me of labyrinth mazes I used to make to torment people x) (fun times!)
