The games already created are fine, however the interface to select and play them is NOT user friendly. Where the game fails, and I mean FAILS, is on the ability you have to custom make your own pinball machine.
The interface takes some learning and it is not designed make it easy to set up your own table. In theory you drop and drag the various items onto the table you're creating but in execution it's excruciating how difficult it is to select the item you want (the bar of options scrolls past you far to easily) and to place it (the table tilts and swerves far too easily. They need a landscape mode and a simple zoom/pan feature for building the machines. period.
Now, the EPIC FAIL part of the process. I was very patient and took my time to do my best building a table (or TWO) because I didn't have to be too harsh to the program, too quickly. Twice I tried to save a table, after a small but time-consuming amount of work, and the program CRASHED! Whats worse? The files were saved as un-retrivable, blank pages so all my work was lost both times (saved as an empty file).
I give the programmers one star for effort, but the execution leaves much to be desired. Would almost be a better program if you could design it on a computer website (this is too much work for drop and drag) and upload it to the cloud, or something, for retrieval.
