Had a play of your game in this video here, where I give my thoughts while I play. Hopefully it's helpful feedback.
Overall I had a good amount of fun playing, visually it looked great and the puzzle were good and logical. My only major criticism is more could have been done to lead the player with those visuals. For example, I couldn't tell there were drop areas I could fall into (until I did by chance) because there was no visual differences between a ledge that had an invisible wall and one that didn't. I didn't realize there was a gap I had to get over in the room that introduced the black rod for a quite a while.Also too many of the important visuals, such as the text and some puzzle pieces, didn't contrast enough with the set, making them quite hard to see.
Apart from that the presentation was great and the puzzles gelled well with your mechanic and felt natural.
If you have time I'd greatly appreciate it if you could give my game a go to, happy jamming.
