About this gameFull description from Steam
Antimatter Dimensions is a highly unfolding Idle Incremental game with multiple layers of unlocks, prestige, and achievements. The basic goal is to reach Infinity and receive an Infinity point, which can be spent on various upgrades to increase your overall production. After Infinity the game has just begun, as there are much, much more to discover. 2 years of updates, then 4 years of pretending to update behind the scenes Multiple challenges, ranging from minor alterations to major challenges that forever change the way you play the game 100 Steam achievements, but even more in game! Less than a hundred perks, 0 talent and some miscellaneous upgrades too complex to go into detail about An obscene amount of automation, including a custom scripting language. AD also happens to be about unlocking new stuff and automating all stuff. Helpful tutorials in the helpful help page. Two black holes to explore, 0 mini games, 4 “pets”. If your glyphs start speaking to you, please see a doctor We added a shop! Antimatter Dimensions was originally created in 2016 by Hevipelle as a web based game, however it's development has since expanded to have multiple developers, and even more testers. During the first years, it was updated rather often, sometimes updates within 5 hours of each other. But after the Dilation update in 2018, Hevipelle and the team started working on the Reality update. Over 4 years later, the update is finally out, along with the Steam version of the game!
