This is amazing! I love the models and shaders, the gameplay is so interesting but maybe a little too hard (it might have been your intention to make it hard but I had +10 tries on each level. )
It's really impressive for 7 days. You know there's something wrong with the system when a game like this only has 3 ratings :D
I just have two small suggestions:
-Increase the pick up range of crystals, they're so easy to miss specially in second level with moving platform.
-It's really hard to aim properly, I suggest you change the aiming system to point at the cursor or have a better indication on where the character is aiming.
Btw did you use HDRP?
