I tried this game now.
It's a run-jump-shoot type game with some interesting things...
It seems to be an Unlicensed Chinese game.
The player can break walls in various ways.
One way is to jump up under the wall, just like Mario.
(Speaking of Mario, the level does not scroll to the left.)
It's also possible to break the floor in front of you or under yourself...
Some walls contain power-ups (red/blue balls) that do various things.
(You can usually see them behind the wall.)
The Select button makes the player die and thus restarts the level. (Ctrl+A, anyone?)
(The default mappings in FCEUX are s=Select, d=B, f=A, so it's too easy to press it accidentally.)
Why did they add this? Is it even possible to get stuck?
I gave the Russian description to Google Translate: (emphasis by me)
"Hell Fighter" - this is a terrible name of this game. In fact, everything at least badly. You - the guy similar to Prince of Persia. Walk and throw arrows at any evil spirits. The hero can even break the blocks as in Super Mario Bros. But salt is that it is impossible to guess what the unit can shoot and what not. Die Prince on our one touch. But how! You turn into a skeleton and start the silly dance. Oddly enough, but the Select button is responsible for the suicide! Better not to swing there on the NES games much better.
Hmmm...
And I found something (other than the player) that looks like it was copied straight from PoP.
Can you find it on this screenshot?
