Well, the graphics is amazing, obviously.
The interaction was a bit wonky though, I needed to look exactly in the right direction to activate pillars. Probably having pedestals activate when the character is in certain radius, as you've mentioned in other comments, would be more convenient.
The puzzles were a bit similar, these one-way loops where you needed to acquire a crystal were slightly overused. These had some variation to it though, so it wasn't annoying. The last puzzle (4 pillars thing) felt a bit fiddly as the only solution I could see was brute force. If there's some logic to it, it would be nice to have a hint of some sort.
Considering that's done in 48 hours, nice job!
