Anyone knows anything about this game?

It looks it was never released and what we see is just some pre-alpha development state.

found some discussion about the game

1. the problem is it is not possible to finish first level (or I just don't know how to do it - but i don't think so)

2. You don't really have to play this game to notice that. You can just use right shift and arrows to jump to adjacent chambers. It is good to do it with cycles=1000 in dosbox so that the character doesn't accidently move (and start falling) (with higher cycles don't jump chambers too fast). If you encounter a fight you can just hit space to leave the fight and continue jumping screens.

3. You can help yourself by looking at this map someone made

Top right chambers with elevator are just non interactive animation that take you to the next level

3. A reason for not being able to finish the first level looks to be that chambers are not placed in the right order.
If you are familiar with original Prince of Persia you know that adjacent rooms not only match that you can walk or climb between them but also by looking at sides/top/bottom of each chamber you can tell how the side of adjacent chamber looks like (whether it is empty, has a brick or a floor).
This happens provided each chamber was properly designed of course. I can also see this rule in Cruel World, but not everywhere. This may be considered as not important in places you cannot reach or in some places that just make you die when you fall. This may also be a bug. Check for example the map for 4th column of chambers in second and third row - they don't match: you can fall but cannot climb up. You can see that on the video too http://www.youtube.com/watch?feature=player_d … KmQC_5O4M&t=121
We can call it a bug if you don't have to climb up and can finish the game just playing forward. But it looks the chambers are arranged the way you cannot finish the first level at all.

4. I also see some more less important bugs. Like the dragon walking out of the wall at the beginning. The stone falling out of empty air and crushing you. Green shade of clouds in the intro. The first paper you read after defeating first skeleton is empty (no letters on it), Later enemies have papers with text.

5. It is also strange that you can access jumping chambers with "right shift" and jumping levels with "dot" and "comma" without entering any cheat code.

6. It looks that jumping between screens can access other levels too as i see the same chambers and their arrangements on other levels too.

8. Do you happen to see any credits in this game so we could try contacting its author? The only name I see is when exiting setup.exe but i guess that doesn't have to be someone who had much to do with this game. I don't see anything in intro and ending (i finished the game by jumping to last level and encountered a boss by jumping chambers. I defeated him (was easy), watched whole outro and no credits there.
