Timeshock free version changes

With the new, 1.20, version of Timeshock for iDevices a major change has been introduced. The free version is no more score-limited but it is now supported by ads. Practically this means that when you start the game you are greeted by the following screen 

Unless you have purchased a standard or deluxe version you must watch a short, typically 15 s, video and then you have access to the game. At the end of the three-ball game you can also purchase extra balls, again by watching a video.

In order to test the ad-supported features I had to borrow an iPhone and install Timeshock since I have the deluxe version already installed on my iPad. In fact I was not able to verify whether an extra ball purchase feature exists on the deluxe (or standard) version, so your feedback on this point will be most welcome.  

Be that as it may I find that the ad-supported feature is less frustrating for a casual player, although if you are a pinball fan you should not skimp on this and purchase at least the standard version. Remember the revival of the remaining ProPinballs relies solely on the commercial success of Timeshock.
