If you'd like to help with the translation of the android version you can join the Crowdin project using this link: https://crowdin.com/project/antimatter-dimensions/invite?d=65a5i4j645c593u4n4a3e5m4f3137363c3
Get a macro, it'll be useful until the autobuyers are better
This (Android) is the one I used. You can set up multiple "fingers," and they can swipe
This is not really a problem with performance ticks, your browser is throttling inactive pages by default. But the window does not actually need to be visible, just make sure you don't minimize it, leave it running in the background. Also look at this guide to disable tab throttling.
And try disabling other options, like "Throttle expensive background timers", "Enable resource load throttling", "Page Almost Idle", "Proactive Tab Freeze and Discard".
If nothing helps, try Firefox, it's much faster than it used to be when AD was first released, and anyway is better than nothing. Import/export feature makes switching very easy.
I refactored the whole app from Java to Kotlin which might be a part of the cause.
I've done this because Kotlin has a lot of things that Java lacks, for example: operator overriding, safe call operator (?.), string interpolation, default values for paremeters, extension functions, lazy properties, and a lot of other stuff (https://kotlinlang.org/docs/reference/idioms.html).
Along with the refactor to Kotlin I also refactored the code for Dimension purchasing to bring it up to date with the code in the web version of the Reality update. The code is now simpler and less prone to bugs, but it might also be a part of the cause for the slowdown.
If at any point you feel that you don't want to wait that long during startup you can always lower the amount of offline ticks and use the offline generation milestones. Personally I always use 1000 max offline ticks because I don't like waiting.
Ok so I had to wait 10 minutes for the imported save to load and the game completely bugged out afterwards, everything costs infinite antimatter and I lost all my infinity points, refreshing the page makes it even worse, maybe it's because it's an export from an older version without the extra "breaking infinity" stuff??
