In the past two days I was playing this mod.
Level 1: Needs some perfect positioning for the jumps. I entered the level door using a glitch (was it intended?)
I don't know how to open the gate at the big potion. I know that the button is behind the closed chomper. Perhaps the blue potion opens the chomper? But how to drink it without bumping into the wall? From the other side?
Level 2: Also needs some positioning. Again, I don't know how to get the big potion. Perhaps the kid could somehow fall in? And how to get out?
Level 3: Ctrl-A had some job here!

The skeleton is... colourful?
Level 4: Interesting idea(s) in the first room... But I can't go further than the second guard. Either the kid falls into spikes or the guard stabs the kid (but then the guard falls into the chomper!

).
Level 5: Be faster than the shadow! Again the same glitch as on level 1.
Level 6: 10 run jumps are a bit boring... but the only way to
advance.
I could get the big potion, but the gates close too soon.
Level 7: Am I right that some loose floors are activated by buttons?
It seems that the top-right loose floor usually falls (after some time) without anyone touching it, but sometimes it doesn't.
Easy... if I don't want the potion. Otherwise I need the "sometimes" to happen.
Level 8: This was very easy... the first time. Now I played it again and perhaps it's not *that* easy.
Level 9: Again mostly easy unless I want the potion... Something always closes the gate at the potion.
Level 10: A bit boring with going left-right-left... through mirrors! Needs precise positioning.
I could open the exit, but I don't know how to get there.
I could also cause an integer overflow, but I don't know if it was intended. It does not seem to bring closer to the solution though.
Update: but it does! I also found the other (less boring) solution.
Level 11: The gate closes before I can reach the exit. (Climbing 4 rows is long!)
Update: that gate has to be kept open.
It's a good thing that guards wait a bit when the kid is bumping into a wall.
Level 12: Again some interesting ideas with the special events.
Level 13: The beginning of the level is randomized, because of the loose floors.
Jaffar was so bored that he played tic-tac-toe... with himself?

I can't get the big potion here. I know how to open the gate at the potion, but how to get there?
Level 14: And yes, there *is* a potion here as well!
Some questions about the graphics:
What is that bouncing thing instead of the flame? A ball?
What are the palace spikes intended to be?
And the mirror is... a statue of the prince in some fancy hat? What is he holding?
Why does the mouse have red eyes? Because it's a white mouse... or because it *closes* some doors on level 8? (evil)
Some other small things I noticed:
The level door is an elevator. Some walls have a peace sign on them. The kid has longer hair.
Jaffar has longer beard. The fat guard has a baseball cap.
