Goblins 5 on steam (out now!)

https://store.steampowered.com/app/2475980/GOBLiiiNS5/

I already played the itch.io version (very weirdly packed in 4 parts) but it's plays just as nice as the older ones, and it's long.
Only issue i found is you can't save in between, and you really have to play level by level.

For some reason only 1-3 are on GOG and not on Steam (although it might still be a possibility now), 4 is just as good but it was very underrated and only sold i believe through the developers site and never on a cd/dvd, that's not legally obtainable right now.
I have asked the dev, but there were some hassles for some reason, why 4 most likely will also never come to Steam/GOG.

He also made this game that never came to Steam or GOG: Woodruff and the Schnibble of Azimuth.

Now available, somehow they keep the annoying screen to choose between 4 parts when you try to launch the game, where it could just be so easily have been put in 1 level selection menu (i mean the first even had that). Also there will be some translation errors here and there, one moment the character is called Oups, and other times Oops, or Ballon instead of Balloon.
