Aww, thank you! Your words really touch my heart!
The truth is, I've been thinking about ways to extend the game somehow, but I haven't come up with too many ideas. Since I originally only had the concept of making a maze with an ending, I didn't even add multiple levels (and even a single one is already pretty difficult to finish).
I've thought about a few things that people suggested in other comments that I really like and think could improve the game, although I'm waiting for the voting to finish before implementing all of that. Beyond those ideas, I'm not really sure if the game can support being stretched much further.
That said, your comments about the game make me incredibly happy. I'll definitely keep them in mind and see if I can come up with some kind of twist after I add the planned changes. Maybe it has a future after all.
Thank you! <3
