I have a bluetooth keyboard, so I decided to do stuff with it on my phone. One of the apps I tried was of course TLA2, and the keyboard worked. It uses WASD, not arrow keys. So I messed around with it a bit more. One important thing is that it doesn't act the same as the ingame keyboard. If you go to level 19 and type "KEY" on the physical keyboard, it doesn't work. But you can still save time (theoretically) by typing on the ingame keyboard open while using the bluetooth keyboard to move. It also lets you jump in level 9, and skip setting the volume in level 34. It doesn't work in level 8, have not tested level 51. You can't double jump (or maybe you can but it's incredibly precise). One more thing: Jump storage. If you pause and press W multiple times and then unpause, you can do more than just a double jump. You can do a triple jump. Quadruple jump. If you do a septuple jump under the middle platform, you can clip into it. Unfortunately, I don't think it's possible to clip through the ceiling.

Ok, nevermind, it's possible to clip through. However, you can't drop down to the level transition. The wall blocks you. If only there was right moving storage.

I tested jump storage on level 79 and if you clip through the ceiling and go to the right (you can do that by just spamming w while paused on the highest platform) it skips to level 80.

Also, in level 47, if you press W 12 times, you can clip through the ceiling. Go right and you clear the level. It might be able to be used in level 48 too, but I just end up getting stuck in the blocks.
