(I was writing my review while playing and I lost everything, here's what I remember I wrote)
It's overall a cool game, but I found two things to improve :
1) Enemies. At some point they can get really annoying. I suggest either you add some weapon, or you remove some of their abilities to make them easier to avoid (like slowing down bats and removing wolves' ability to jump), or at least don't put them in a place where it is impossible to avoid them, like a wolf right next to a bridge you have to pass from below.
2) The player goes waaaaaaay too fast when going to the left/right. This can get really annoying when jumping on narrow/invisible platforms, especially if the player keeps walking a little after the left/right key is released. I suggest you slow the player down and make sure to stop the player completely from horizontal movement when both left and right keys are not pressed.
Other than that, it's pretty fun to play! Challenging enough, ok music, nice graphics :)
Keep up the good work! ;)
