The hint about the title of the classic isometric action game by Sigma Team is actually a pretty big hint toward the title of the game in the riddle. It's almost another version of the same game name (different words meaning approximately the same thing).
Also this game is on Steam but not on GOG, and it was in that Itch Bundle for Racial Justice.
On Steam, this game has 100% positive reviews, 10/10 from customers who bought it on Steam directly, 17/17 overall. Costs $14.99.
The publisher of the game on Steam also sells the software the was used to make the game.
