I remember coming across this game back when it was shareware. It struck me as horribly amateurish even back then, and I skipped it for more polished mainstream offerings like Jazz Jackrabbit.
Listening to this gave me a new appreciation for it though. Much in the same way that shmup elitists take a game like Raptor Call of the Shadows and because it lacks that ultra-hard bullet-hell anti-gaijin NES-arcade-port heritage and was programmed by a white guy it gets derisively called a "euroshmup", I would call this a "europlatformer". It's certainly not Mario or Megaman but it's a good DOS game when you sit down with it and has that characteristic DOS 256-color-gradient chunky charm.
One place I know to find out more about eastern European DOS games is oldgames.sk. Apart from being a good abandonware site, it seems to be written primarily in Slovak then translated into English as a secondary language and they have archive scans of Czech and Polish looking game magazines. They also post the odd local game, not always with an English translation.
It seems there was a good scene in eastern Europe and Scandinavia back in the day, most of which has wound up on the internet somewhere or other, you just need to have grown up around there to know what to search for. I recall being shown some fun little games by a Finnish friend though I can't for the life of me remember them.
