Hey, thanks for your feedback!
It's been a while since I posted this game. This was actually my very first game created with Unity, back in the early days when I was just learning the basics. I used assets from sources around the web, including the mazes, which colliders were generated automatically based on the model's mesh, hence the possibility of some "unseen gaps". But if you stick to the main course, I'm pretty sure you'll be able to go through the levels with no problem at all! I tested it several times :D
Anyway, your feedback is very appreciated and although this game was more of a joke/test than anything serious, I'll make sure to take a look at the bugs you reported in the next few days and see what I can do about it.
Thanks for letting me know and I'm glad you had fun with the game!
Stay tuned ;)
