I'm not a Modder but i'm gonna reply to your post because i'm the one who created and deleted the thread of Head over Heels.
Firstly, you mayne shouldn't know but Yaskashije, our last Genius modder stopped modding these games because the security grade up. It's actually impossible to mod a Genius game, and modder of others platforms left too like Bruno32 of AG.
And secondary, I've found a way to earn unlimited coins fastly and i posted it on the last thread. Results : this glitch have been removed and know it's not working anymore. I decided to share it and now i'm fuc*ed. So see it's not that simple for instance so be patient and see what come in future.
