The game is called
Pacho 98 and it was developed by slovak company called
KiloSoft.
Here is pretty much only relevant reference to the game which I managed to find on the internet. Sadly the page is in slovak so it probably won't be of much use to you guys. The page does not contain download nor any more details about the game like credits for example anyways:
