I am having loads of difficulty getting the Power Gem. Could you help me out here?

I am confused on what to do in the last puzzle in Antti's room. I press the button, but I cannot move. Any hints?

I am still having trouble finding how to get to the next part after komag's room. I have the note that says, "Reach!" and I am next to the statue and healing crystal but I can not find the way forward.

Strangely enough, I am having difficulty finding the room that is supposed to be after Komag's room. Can someone help me out here?

I am stuck in the room with the four slimes with the note that says The Flight of Wealth will Open the Passage To Poverty.
I have already put the correct gems on the altars yet I do not know what to do next.

Yes, I am stuck on the room with the 4 colored slimes.

I am stuck inside of a room on Level 26: Moonmark Tower Level 3 in the room that says "Turn back till you can, there is no way ahead!" How do I get out of that room?

On Level 8. Mentioning the level does seem pretty crucial now that I think of it haha.

I can help test if you still need testers

I am currently stuck and have been for awhile. I have all ready gotten both skull keys but now I cannot find the Purple/ Amethyst Key nor the Key to the top most door kind of on the right side of the map. Any hints for me?
