No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $56.3K — a different platform, not this one.

Mad King Redemption

The Kingdom has fallen to the Mad King, who has used forbidden magic to try resuscitate the queen. But the powers of life and death were too big to handle for him, and as a consequence, the King has lost his sanity. Slain hordes of enemies through careful button smashing! Faithful to a brawler, with the additional strategic layer of a roguelite, the destiny of the Kingdom lay upon your shoulders. Upgrade your brotherhood of heroes after each run to unlock combat skills, artifacts and heroes. BEAT'EM'UP GAMEPLAY Drawing inspiration from beloved classics, we've crafted a beat'em'up experience that combines old-school controls and retro feelings with innovative 3D mechanics. Each of the 4 playable characters comes with their signature combat styles, customizable stats that impact gameplay, and detailed backstories to discover. Every hero has committed a sin. They also need redemption. ROGUELITE PROGRESSION Unlock new heroes, attack moves, and upgrades with every run, while venturing forth in the depths of the forbidden cloister, to look for the Mad King so he can be relieved from his madness. Every run is unique, with randomized elements. Only a united brotherhood of heroes can overcome the Mad King: he is the dungeon master, and he'll grant you powers embued with forbidden magic, to make you stronger, but you'll have to pay a price for that!
