I have found out that the game is freeware so if I find the working copy (the damn sites i have searched want an average of 5$ from me for a freeware game) I will post link here.
If any of you would find it before me, it would be nice if you have posted it

Seems this would be original source:

Edit:
It does work indeed, but wasn't that extremely challanging as I supposed it to be (perhaps I was just too dumb at the age of 10 to figure stuff out, lol).
Neverthless it offers some 7/10 oldschool gameplay.
Also, remember to restart the game (middle of three small buttons, right top part of hud), unless you want to play with everything unlocked from the beggining.
Brotip:
You can discover stuff by using two things on eachother.
