Hey. I have sketchy memories, here they are.
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 ;)
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
you scream like daffy when you die
also it's by the dev of hocus pocus
