I found a more consistent strategy for the Phase 4 end on android / PC bluestacks emulator. Basically you let all the blocks fall then move to the end of the room with the falling blocks and go all the way to the top right. When you do this the blocks behind you will start to fall downwards and make room for the ball to get through. You can also glitch through the gap even if the entrance is blocked if there is a corner that you can get stuck into as the ball will overlap hitboxes with the block that is blocking the entrance to phase 5 and you will glitch right through it. This raises the chances of completion of this checkpoint and getting past it significantly. Now the PC run is a lot more viable due to this room being easier to clear. I am also working on getting a 1.0 version of the game to see if there is any difference in the game on the Phase 4 end so that it may be a better speedrun to compete for. I found a 1.1 version of the game but the end of Phase 4 still is the same as the 1.2 version so we may have to go back further. The goal is to get a version of the game that has the Phase 4 end like this video where the blocks fall slow enough for you to just press forward and not get stuck. I am attaching the 1.1 version of the game to the discord channel as well for you to choose which version you would like to play. Phase 4 might be even more consistent on the 1.1 version but I still have to test a bit more to confirm this. Also, to run this 1.1 version you have to setup a 32-bit Nougat instance of bluestacks as it is a 32 bit game not a 64 bit one and it won't run on the standard 64 bit bluestacks instance. The ultimate goal is to find a version of the game that has the same Phase 4 end as shown in this early video of the game when it was released at 6:36 in this video the blocks don't fall fast enough to block you from getting to Phase 5.
