Not sure what I could be missing; I've gotten the yellow ending and 100%ed all the areas I've found. My best guess is that there's a place where the pause sign can get turned sideways, or something?

hi! I really enjoyed playing through this, and 100%'d all the worlds available. After I saw that there's a second ending, I tried a fair few things trying to figure out how to access the other ending, but didn't have any luck. Since there aren't any guides, I was hoping that someone (or the dev?) could offer me some hints? :>...

In the lowest level of world 2, when I put the right button into the checkpoint, sometimes the lock can be opened, and sometimes it can't.

Maybe there's puzzle mechanics later on that rely on being able to click the buttons, but I found that way of controlling your character in the demo incredibly clunky and annoying to use. Why can't I just use WASD to activate each available button?

I've passed chapter 9 where there is only a single level , but after I finished it the screen went black and crashed with no warnings or errors. I tried to play the cutscene at the beginning chapter 10 by stating the game again and it still crashed. Similar problem happens to the pink cutscene (edit: also the yellow cutscene) in chapter 10. I guess it should be the pink ending but I cannot get the achievement :D ....
