Just bought the extra slots (small bag), when I collected it from the message centre it said 'nothing collected' and I lost the diamonds and didn't get my bag!
Agree with the earlier comments - the sprint functionality seems erratic at best and the cool down time for the laser seems overly punitive. Otherwise interesting game play and graphics, enjoyable (if short) upgrade path and fun to play!
Simple idea that should deliver more considering the basic premise. Very laggy, poor selection on HTC desire HD. Needs more polish, shouldn't be released like this.
Very limited gameplay, no real instructions, graphics poor (to say the least) - at best an underdeveloped idea that has been rushed into release. Do not play.
An otherwise entertaining game is ruined by a poor control interface that requires a level of precision not possible to deliver with the mobile experience. A great shame, as a gem has been compromised by a direct port from PC without consideration for the new environment. 5 star idea, 2 star implementation.
