Hey. I have sketchy memories, here they are.

2D Platformer.

I ran it in dos. My copy, at least, had a game selection launcher menu type thing that ran ahead of the main game. It was separate to the game itself.

Fantasy theme. The player's character may have been a wizard.

Levels consisted of collecting gems (I think) which appeared centre of a tile or position, I mean, at waist level or thereabouts. There would be quite a number of them (hundreds?) in a level all over the place, some harder to get than others, and they all had to be collected before a deadline to pass the level.

An "overworld" of sorts, where you would walk to different areas to enter levels. Some areas needed a minimum number of gems (or whatever the commodity was) to access.

Possibly a vibrant, colourful aesthetic.

Thanks for any suggestions in advance ;)

Xargon?

Hocus Pocus?

I was thinking the same lines, but that overworld feature is missing. Ditto for "God of Thunder".

I almost thought a Clyde's Adventure game

because it's a platformer where you have to collect gems

it's hard

you scream like daffy when you die







also it's by the dev of hocus pocus

Clyde's Adventure Game, that's it. So, maybe I got some details wrong, haha. Thanks a lot :D I haven't seen this in many, many years..
