tl;dr:
Mister Moonboots is free, ad-less, and on the App Store!. Horrah!
A while ago while on holidays without my lappy, I was forced to entertain myself with only an ipad and no internet connection. I found an app I must have downloaded at some stage called "GamePress" - a "make a game by drag 'n' drop" kind of thing. I ended up making a little endless-runner(ish) game. Given the limitations of the software and trying to do real work only on the ipad, I was really happy with the result. I submitted it to the game competition that the GamePress guys were holding, and it won... so, now it's on the app store as a standalone free game:
"Mister Moonboots" It's pretty simple - but quite fun... had a few friends hooked on it (when most of my games they just politely smile). Though, I'm probaly most happy with the
dubtastic theme song I made. To the moooon!
