I remember a game making tool with very Windows 3.x graphics. Sparse, white BG, black lines, 16 colour palette. Made adventure games where you move room-by-room. Sci-fi setting. No character visible, just click on things. Built-in items like coloured keys. Closest thing I can find is MacVenture. There's a window for the room, one for text, and one for inventory. I remember octagon-shaped rooms? Maybe these was a map window too.

I remember a shareware version of a neat breakanoid-type game where your paddle was carried by a cartoon professor (like Thunder and Lightning), and you could tilt the paddle to different angles. I thought it was called Nyett III, but turns out that's a different game (a Tetris clone). Probably for DOS, but maybe Windows 3.x. Some time in the 90s. Graphics were nice, so maybe VGA or SVGA.

Have a very vague memory of an adventure game where you had to hunt down the Kelly gang. Maybe a bit like Carmen Sandiego? I remember CGA graphics. Never tried looking for this too hard, just remember playing it in class a couple of times.
