Shop Heroes

Been playing Shop Heroes for about a week now and really enjoying it - but now its getting abit grindy and considering it has been around for 3-4 years everybody is mostly at end game point. Really hoping someone can point me towards a hacked APK or someone who know a compatible mod. Mostly interested in gems. Thanks!

I've been looking for one over the years, never found anything that really worked :/ I just had to suck it up. I'm 4+ years in, and now brain dead...
