Idk, game was a fine difficulty for me, so you don't really have to worry in that regard. I loved the black and white graphics, they were really well done! The runes on the floor looked especially good. The player animations were all really good, especially the wall slide.  So good job, there are a lot of things to be proud of in this game! A few points of feedback:

- The wall jump felt really unreliable, it would sometimes send you downwards instead of upwards

- I think the way you programmed the wall slide is by making it send you downwards at a constant speed? You should make it so that only happens whenever the player is already heading down, because it felt really awkward to have my jumps cut short and instantly start sliding downwards by touching a wall.

- The ethereal spirit kind of baits the player, I thought it would let me walk across spikes since they were right next to where you got the spirit

- It seems that you run out of time to make a big level, but if you want to expand the game in the future, you should spread out the powerups. When the player gets them all in a row it is kinda useless to have them as powerups at all since the player plays most of the game fully powered up.

Overall, good entry! It has a lot of things going for it

The Graphics looks nice but it is to difficult for me

always remember, if the difficoulty feels just right, then its to hard for the player.
