Tip:

This application allows interaction using a physical keyboard, so it is important to note that the smartphone needs to be compatible with OTG (On The Go) technology.

For a better experience you can customize a cover for the keyboard using cardboard, leave access for a key at each end, build a larger button with cardboard and paste on the key to be used.

If you have a little knowledge in electronics you can disassemble the keyboard and use the logic board, build a sturdier box with larger arcade buttons.
Get the hint, be creative, use an old keyboard and reuse the scrap.

If you do not use a keyboard, the touch function of the unit will function normally.
