Oh... after 2 hours it gets so damn repetitive... bit underwhelmed after a great first impression. There is just no new content - you have seen the entire game (apart from upgrades) after less than an hour. Compared to other games at half or less the price, its a bit of a bad surprise. What doesnt help is that the game tends to crash very very often (iPad Air 2). As this often happens far into a level, I lost a lot of progress (levels have to be restarted). @Developer, if you read this: please let me turn my device 180degrees! ATM the screem orientation is fixed, which is just bad. Will take your programmer about 10 seconds to take care of this!! Thank you!!
