Hi and Thanks a lot for the feedback!
I am very glad that you liked the puzzle element and that it separates me from the rest, A common fear I had during development was to make something too similar to others project as my idea for me felt very basic. But its lovely to hear that I succeeded to make the game stand out!
Yeah, both player movement and the "see through" shader will be improved. But first and foremost the ledge bug will be fixed as it is very nerve wracking even during play-testing. And the "see through" radius will stay the same during most of the gameplay, only while going through something like the big block in the existing level the radius will increase to increase visibility! But I will have you feedback in my head during these fixes! :D
Sound, Options and Credits was not prioritized for some reason. But I did actually add sound yesterday which felt really nice, also as a bonus to that the options now has both Sound and SFX sound settings. And the Credits will contain the text in this submission and also the sound credits! :D
Thanks again for the kind words and for playing! :D <3
