have you tried using the reset room option in pause menu (escape)?
So what I believe has happened is you ended up in a late game area using abilities in a combination I hadn't thought off. You shouldn't even be in a red room without the ability to rotate the rooms.
I will come up with a solution and patch a fix. Thank you for playing the game and my apologies for the issues.

Thankyou for taking the time to take the screenshot as it has confirmed my suspicion.
An updated version is now available for download which solves both this and the mouse issues.
Upon downloading the new version and loading your save (saves from previous versions will be auto detected), a blue warp will appear near the right wall. it will take you back to the entrance.
Overall congratulations on discovering this sequence skip, and I truly give my apologies for the experience being ruined as a result of my oversight.
yeah i visited the 4 red rooms.
game just hung itself in that dream sequence, so I will retry it.
edit:just tried.
it runs until the cat stops moving and the plyers does an automatic jump,
stopping in mid air, game frozen.
Apparently some cutscene or such is to be played out which freezes the game for me

To clarify the small crystals are only used to unlock the gates and you don't need more than 4 to complete the game.
But as long as you are enjoying the game that is all that makes me happy. Do let me know if the end of game freeze still happens, remember to redownload the latest version in case you haven't already.

I have released a new version that adds a warp into the red room that will take you to the exit. These should apply to your save retroactively.
