Thanks for the feedback! The part where you're stuck at actually has two paths. You can grab the chain in the first room and then jump precisely down the hole in the centre. Alternatively you can go through to the right where you will meet the room with the laser eyes shooting down towards a poisonous pit.
What you're supposed to do here is to see that the lasers are disappearing at different spots indicating that there are invisible platforms that you can jump on to get across. I get it now that it might not be that obvious and so I might make the laser give more feedback when hitting the invisible platform.
As for the game's future, It will probably not get any more content updates. I might change my mind though so we'll see :). I will be providing some fixes and patches that I feel are necessary through feedback like yours.
I really appreciate you taking the time to write this to me and thanks for playing my game!
