Cool mechanic ! It's awesome seeing other shadow platformers and the different angles each one takes. The puzzles are really clever too, although so far I'm still stuck on the last level. The difficulty spiked quite a lot in that one (no problem though, it's quite common in jam games).
One thing that I would've liked as a little QoL change is showing the max range your shadow can travel from you. I had some difficulty determining how far my shadow could go before being teleported back.
Overall, awesome game !
