Hiii, I've made a 100% walkthrough without being hit and I wanted to share it with you along with some feedback about the game ^^ Hopefully it helps :D
-The concept of the game is pretty good and the execution overall is quite awesome. I can really see your experience making this kind of 3D platforming games ^^-The gameplay mechanics are reaaaally good and combined with the open level design style you've used the posibilities to get through the game are infinite. In toree games I always thought that the controls could be improved, but this time I have no complaints about it, this time you really nailed every playable aspect of the game ^^.
-The visuals are quite good, but I'll say that the level with hanging blades could have looked a little bit better with some extra platforms/props around it since the main tower looked amazing.
-I really loved the little easter eggs that can be used later in the post credits level :D
I really loved this game ^^, but I have a question: Have you considered creating a bigger game with this style and gameplay mechanics/concepts ?
Regards
