Undertale controls

So after just a few years I needed to play Undertale on my telephone once more. Everybody appears to play this new model with built-in controls, the issue is that after spending dozens of hours on this sport on my telephone years in the past, the analog stick design is horrible. I keep in mind having a gamepad app (second picture) that may let me swap the keyboard with the gamepad proven and it was very snug, the motion controls had been simply 8 buttons as an alternative of an analog. Does anybody know what this gamepad app title was? I can't discover it on play retailer
