YMMV / Antimatter Dimensions

• Breather Level: Ra, a mostly-passive Celestial, follows V, the most active, giving players time to relax and focus on other things for a while.
• Disappointing Last Level: After you beat the game, you have to fully reset everything except for your secret achievements and option settings. This also gives you one skin for your glyphs. There are 35 of them. To truly beat the game, you have to go through all the game's content 35 times, with no boosts or headstarts.
• Junk Rare: A Rare (or better) Dilation Glyph that only has Time Theorem/sec generation or Antimatter Dimension multiplier while Dilated effects is practically useless, but still rare. Other Glyphs can also fall into this category, depending on whether their effects are useless to your progression stage.
• Memetic Mutation:
  • 5 hours until the update^ExplanationWhen someone asks when the next update's going to come out, "5 hours" is the standard response. For the time the Reality update was in Development Hell, it had become increasingly inaccurate, especially when the Steam version was given the release date of "In 5 hours™".
  • The 9th dimension^ExplanationThere are only 8 dimensions of each type. The nonexistent 9th dimension is mentioned in many news tickers.
  • 1.79e308 / 1.8e308 / 1e308^ExplanationThe antimatter requirement for infinity, which is the largest finite number that can be represented in JavaScript. Many news tickers include this number.
  • I eat ass^ExplanationA phrase that was used by Boo in the Discord server. The "Like feasting on a behind" achievement is named after it, and typing the phrase in the import save box unlocks a secret achievement.
  • Hi. You are here. You are trapped here. Infinite/Forever/Eternal.^{Explanation (spoilers)}Upon dooming your reality, Pelle, the 7th celestial, says this to you. Used to greet players who reach the final progression channel in the Discord server.
• Squick: There is an Achievement called "Like Feasting on a Behind", which has rather disgusting implications. The picture for it on the web version shows a donkey (aka an ass), and the picture on the mobile version just has the text "I can't draw this like really what do you expect come on".
• That One Achievement:
  • In terms of early-game achievements, "Zero Deaths" is one of the most difficult and time-consuming to obtain before you get Infinity Dimensions. You need to complete a challenge without any Dimension Shifts, boosts, or Antimatter Galaxies, and the only Challenge where this is remotely possible is Challenge 3, where the first dimension grows in power at an exponential but slow rate. This will take over 20 hours without any Infinity Dimensions, which you only obtain in the mid-game. This eventually got pushed down to become a mid-game achievement.
  • The mid-game achievement "How the Antitables Have Turned" can be missable thanks to how it works: You need to have your 8th dimension multiplier higher than your 7th, your 7th higher than your 6th, 6th higher than 5th, 5th higher than 4th, etc. This is especially tricky once you get certain upgrades that improve your 1st dimension multiplier, causing it to become too big for the rest to surpass it. As such, it was pushed up to become an early-game achievement, where it is indeed easier to obtain early-game.
  • In the late-game, there is "Long lasting relationship" which requires you to produce more Infinity Power per second than your Infinity Power for 60 consecutive seconds. It is hard because Infinity Dimensions don't produce Infinity Points, and maxing out them makes your Infinity Power production only briefly exceed your Infinity Power. To get the achievement, you have to manually buy ID1s one at a time at a certain rate for 60 seconds and if you mess up the timing even once, the timer starts over. However, there is a Time Study, which makes this much easier, and allowing you to get it automatically without any strategy eventually.
  • If you liked Zero Deaths, this one is for you. "When will it be enough" requires you to reach 1e18,000 replicanti. This will take over 12 hours to get and unlike Zero Deaths, this 12-hour time is with every possible replicanti speed multiplier before Reality, which requires you to get all achievements to reach.
• That One Level: Some Challenges are far tougher than normal when initially unlocked. Of course, once you have obtained enough IP, skills, or achievements, they turn into a breeze.
  • Challenge 9 when initially unlocked requires you to do things manually, because whenever you buy 10 of a dimension or tickspeed, everything else of equal cost will increase to its next cost step. This can make things unwinnable and thus have to force a reset to retry.
  • Likewise, Infinity Challenge 5 when initially unlocked requires good micromanagement. In addition to having Challenge 9's restriction, when buying dimensions 1-4, everything with costs smaller or equal increases, and when buying dimensions 5-8, everything with costs bigger or equal increases. When buying tickspeed, everything with the same cost increases. This means that you can make things impossible until you reset if Dimension 8's cost gets too high. Like regular Challenge 9, this requires very careful planning. Infinity Challenge 4 only has the last dimension bought producing full power, so micromanagement is needed as well.
  • Eternity Challenge 11 is less of a challenge and more of a total slog. You have to use a specific Time Studies setup, wait for Replicanti to build up, and get a bunch of Replicanti Galaxies so you can get enough tickspeed to progress. Under optimal conditions, EC11x5 still takes more than two hours to complete. Even the first few Realities won't make it go by much faster, with your only saving grace being a Replication glyph. Thankfully, an update divided the base challenge goal by 1e50, making things noticeably faster.
