Huh, not too shabby! Navigating these labyrinths took me right back to playing Golgo 13 The Mafat Conspiracy on NES (or perhaps more appropriately, Jurassic Park on SNES?)
The game overall has a very polished and quality look and feel to it which enticed me to play more and more. The concept is nice, but I'd admit I found my attention flagging around 10 levels or so as the levels didn't feel like they were increasing in difficulty in a satisfying way. They were introducing new mechanics but it never felt like things were stepping up significantly: everything was just a bit too easy and bite-size, and the levels just started to blend together in a blur.
Again, while this didn't quite get me, it's not a bad idea, nor a bad attempt as the construction behind the game is solid, so I'd definitely love to see future games from you as you look to have some decent chops.
