Hi, this is Cursed Gem: https://www.speedrun.com/cursed_gem

A excellent precision platformer game. Due to its first release anniversary it's FREE forever in Steam.

It has leaderboards in game and a lot of records to beat in Speedrun.com

I wish you have fun!!

I don't know... Infectonator 2, maybe. I played a lot Dawn of the Dragons too although it was a bad game lol.
