I figured out a way to play Phases on PC. All you have to do is download Bluestacks and login to a google account (can be a burner) and download an APK of the game Phases version 1.2 by Ketchapp. Also make sure that if you download Bluestacks and the Phases APK to go to > Settings > Preferences and click the disable ads as it is free to disable them and makes the game a lot nicer to play. You can also go to full screen by pressing F11. I uploaded the APK File in discord so to download it directly please go there.
I also figured out how to make an instant restart bind and remap the arrow keys to a and d through autohotkey for the PC Version of the game. And I also made a reset bind as well and a bind to click the start screen so you can play the game entirely on keyboard with no mouse input. Just download autohotkey and download the ahk file in the announcements channel in the discord and drag it into your ahk folder.
With this, speedrunning the game on PC is completely viable but the times will likely be vastly different from the IOS version of the game due to many glitches/time saves not being able to be done on the PC version that are easily done on the IOS version. Also the ball moves right and left slightly faster on the PC version than the IOS version. Although there are some differences (not to mention the much harder to do consistently Phase 4 end) I think it will be a very fun speedrun to compete for due to the ability to play it on PC and the instant restart binds and key remapping. It seems to me that the PC version that is available is the same as the Android for all intents and purposes so the leaderboard for Android and PC are combined while the IOS Version is very different and is separate
I am posting this long format update here in case anyone wants to run the game still. Firstly I will say that the IOS version of the game is only possible to be run if a few specific conditions are met. To run the IOS version of Phases (the fastest version) one could have an old iphone / ipod / ipad
