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 $92.7K — a different platform, not this one.
Montabi
A Creature-Collector Roguelike Deckbuilding Game. Assemble your team of three Montabi so that you can outsmart the bad guys and save the city! If you're going to be the big hero and save the city, you've gotta get some Montabi! Each Montabi has a unique set of skills, giving you and your party of three endless combinations of options and synergies. Collect gadgets, equip charms, and chart the path to victory! Train your Montabi to grow stronger, unlocking new moves to enhance your team's strategy. As they level up, your Montabi evolve into more powerful forms, gaining new card abilities and expanding your tactical options. If you work together, there's nothing you and your Montabi can't achieve! Deploy your best strategies to beat up the bad guys in a unique 3x3 grid-based system. With every Montabi's unique abilities, you'll have endless options to outthink the competition and win the day. Just make sure you rest up at a cafe every now and then to recover those hit points! Select from diverse trainers, each with a unique playstyle. Do you wanna put your team in the perfect position, get right up in their faces and duke it out, or buff up your Montabi with a hearty meal? When the city's at stake, everyone pitches in! Just make sure to stay safe! Like the king in chess, if your trainer is defeated, the game ends. 60 Montabi planned for release, each with a unique and distinct playstyle. Choose your favorite!
