10 Second Life by CodeNMore
This is probably my 4th game that I have actually completed, I believe that for just a few hours (in my case ~5 hrs) it turned out quite well for me. Please check out the game and let me know if you had fun with it! YouTube.com/CodeNMore
It's a bit hard to get into T-junctions. It's frustrating to restart a level because I was too slow getting into a T-junction. Also, personally, I don't like luck part in games. For example two exits where one is wrong or multiple paths where some have invisible walls and I can only choose randomly which one might be the right one. I stopped playing at that point.
I like your concept.
