liked everything here. was fun right away, controls great, sounds and visuals are good to.
liked the extra speed down slopes
also some possible bugs:
have trouble hitting the ghosts right next to you for some reason(both with torch and gun)
when shooting, it does look like it shouldve hit sometimes and didnt(like it goes through the ghosts looking guys)
also seem to shoot occationally when i teleport even though i click once?
there were furstrating blind jumps when teleporting onto platforms to destroy the crystals
crystals also seemed indistructable sometimes? maybe i wasnt hitting them? there wasnt really feedback that told me what i was doing was working
also i take damage from nothing sometimes if i jump right next to the crystals
overall really nice work!
