Man, I love how there's dialog, and that troll definitely got me. I kinda like that I can jump with many buttons but it was a little confusing for me at first since I couldn't wall jump with enter and the wall jump one only works with space or w. I don't know if that part is intended.
I do love the idea! But I find a bit issue with this part of the map where I ran to the right and I just died. I'm not sure if there're other issue in other section but I do recommend to block off the non-intended ways. I thought there'd be terrain over there since in the early map section I could go into different directions for pathfinding(which I really love).
I do really like the concept of this game, I find it really fun. I'm a little confused why we can place spike, though.
I do recommend to put more frequent checkpoints. I kinda died a lot X"D
Great job!
