Just buy it you will not regret it.

The fact a game of this quality can be played at 5w of power on my Ally makes it an easy recommendation, So much so I bought it on GOG and Steam. I you love classic pokemon and want something that can distract you for hours without hammering your Steam Deck/ROG Ally/ etc handhelds battery then this should should be an easy pickup for you. Its like Pokemon if Nintendo still cared about its customers, truly made with love.
