Evaluation

Gemporium launched on August 7, 2025 and received several post-launch patches and quality-of-life updates. On August 6, 2026 — the game's one-year anniversary — the developer shipped the Gemporium 2.0 update alongside the paid "Amber & Amulets: A Gemporium Side Story" DLC, adding cosmetics, controller support, new mine floors, and additional story content. Both DLC entries in the game's catalog are now released. In that same August 6, 2026 announcement post, Merge Conflict Studio explicitly stated: "we do not expect to update Gemporium further" and that the team would be moving on to full-time development of their next game, Pelikeeper. A follow-up bug fix patch on August 26, 2026 (Patch 2.0.15) reiterated this, noting that now the most urgent bugs have been addressed, "our attention is turned back towards full-time development of our next game, Pelikeeper." The developer has been transparent throughout that Gemporium is a finished product and future efforts will go toward Pelikeeper.

Evidence

Post-2.0 bug fix patch notes confirm that after resolving the most urgent bugs, the team's attention is 'turned back towards full-time development of our next game, Pelikeeper,' reinforcing the completion statement.

About this game

Grow your small gem business in this short, casual simulation miner, Gemporium! Manage your time wisely between mining gemstones, refining them for more profit, and selling them to awaiting customers. After your Grandmole goes on vacation, you’re in charge of running her shop, and you quickly learn it also comes with a price of massive debt. Now, on top of building your business, you must appease the Loan Shark without going broke!

Gemporium features a timed day cycle where you have to balance completing tasks and running the gem store. Each day consists of:

Explore deeper and deeper in the local mines to stock up on gems of different rarities. Utilize various mining tools to prevent cracks and maintain the highest quality product for your shop!

Polish and prepare your recent finds in the mine to convert those lumps of rock into something collectors adore! Unrefined gemstones sell for way less than their refined counterparts, so make sure to visit the refinement table before you set up shop.

Sell your stockpile of gems to eagerly awaiting customers, but make sure to keep their tastes in mind to maximize your profit and increase your shop's reputation! The shop is only open for a limited amount of time each day, so don't be late!
