Overall for a 3D project not bad for a week worth of work. some things to note for feedback
the crystals were a tab to fast, and with the movement made it a bit hard to counter.
The gun should probably have some more feedback, even somthing such as the hitmarker expanding as it was shooting wouldve been cool
now for some artistic opionions.
the gun was a little out of place, it felt like a spacey dream-like world, i think you couldve used some sort of other item to make a more coheisive imerrisive world.
overall my summary is
with better movement, more feedback and slight artistic changes this game can be improved exponentially.
the gameplay is there and it has potential!
