Hey!
We're currently cooking up an Android version of OESE. It's early stages and we need to test some things but we're super excited to announce that soon you'll be able to play OESE on your tablet!
It's hard to say when this will be done as we'll have to move the HUD around a bit and optimize some things but for the most part it works pretty well and feels really nice.

Thanks!
