Interesting mechanic! I like puzzle platformers. Great job!

Really nice call adding a tutorial, because I definitely had a bit of trouble getting used to all the controls!

I think the environment pixel art looks really nice. It's a bit of a shame that the spectral double mechanic isn't pushed a bit further, but it's already a cool idea.

It also feels like it's missing some SFX, but overall, good job!

Very cool concept and visual theme! I really like that you went a bit further with the limitation in that the enemies were weapons, but also tools/keys to progress. I am glad there was a tutorial, but everything felt pretty intuitive once I got the hang of the controls (though the scream was listed as right-click, when it was left-click for me).

I would say the astral projection ability could use some tweaks. Notably, it seems the camera jumps from the last location you used it, which kept making me think I died or the camera was glitching. I think it would also feel better to remove the need for it to be close to the player to "recall" it. Overall I think it can become a very deep mechanic.

The puzzle/challenge progression was great - the last room took me several tries. I think you did very well with the level design within the short time frame.

Lastly, some sound effects would go a long way in adding to the satisfaction of throwing a crystal through a wall or an enemy's face.

Well done with your game!
