I had this with Septerra Core. Played it with my sister as children, but we couldn't figure out how to do anything other than just walking around in the starting area, so we dropped the game.
I picked it up again as an adult in 2014 (took me years of occasional attempts to even figure out what it was called), and it was quite a letdown. Copied from my Steam review:
The game lacks any kind of tutorial - the player is told to go to a certain place but there isn't a single pointer about where that place is and how to get there. Had to google it after wandering around all of the small explorable area and still not finding it — the key was to click on a totally unmarked area on the "map".
The cutscenes are missing (because of the "too modern" QuickTime version, according to other players on the support sites), and the audio is weirdly clipped off the end of the character's lines. The battle doesn't seem to work, enemies just slowly kill the character while the player can't do a damn thing — there isn't any option to attack or do anything else in battle.
