Console decline
I don't think that there are any worthwhile exclusives on CD32. I'm not sure if there are even any exclusives on it. The best games I have for it are UFO: Enemy Unknown, Simon the Sorcerer and Super Stardust, all of 'em available on other platforms.
Btw that port of Oscar is horribad. Jump is assigned to d-pad even though there are 5 unused buttons on the controller. Using up for jump in a platformer is like one of the seven deadly sins of game design along with QTEs and cover based shooting. Shows how much Commodore cared about the platform if that thing was published by them, there was 0 effort put into port. The actual cover art for that thing is just a piece of white paper with the words "DIGGERS" and "OSCAR" on it like 10 times and there's no cover art for the backside or the side of the jewel case at all. I wonder how much that abomination sold for brand new.
There's (The misadventures of) Flink, but afaik the CD32 version is quite/very rare and not as good as the Sega CD version which is the best version out of the bunch (CD32/Sega CD/Mega Drive)
