Hard to fight against a clock counting up...
I'm sorry to say, but there seem to be a number of issues wit this game.
I suppose the first and least technical problem is that there really doesn't seem to be any sense of advancement. Every maze solved leads to a try again with no progression or change in the game. Even a change of background scenery might have mitigated this issue.
Presentation: These things make the game feel less polished or finished.
Cursive fonts are fancy, but also harder to read. The timer starts counting even while in the intro dialog screens. The Easy/Medium/Hard buttons, if they actually work (and I'm not sure they do) don't show their state. The play and pause buttons could probably be combined into one button that, again, should show its state.
The walls spawn into the rest of the UI area, which looks very sloppy. The walls spawned counter also got stuck for me.
I also noticed several spelling errors. A quick proofread never hurt anyone. ( And now I will invariably mistype something here, of course. )
There is a very glaring gameplay issue here that I encountered, in that it's possible to turn off all of the walls by holding 1, 2, and 3 down. I'm not sure what you intended, but removing all of the walls makes beating the game almost trivial. As well, when doing this and then beating the level, the walls stay stuck off, and won't reappear until I hit the number keys again.
I hate to sound so negative, but I do want you to improve on your work. Keep at it!
