Repetitive, boring and done before. Firstly, why the penalty for pausing? Second, is it too much to ask for an indicator of when the invincibility is about to wear off?
I loved it, morale adds a nice twist to the game. Anyway, 4/5. A World War 2 sequel with different countries (not just America vs. Germany) would be nice.
I'm not actually a big fan of 'tower games' but this is an exception. First, it's addictive. Second, it's (sort of) original. I especially love the way you can combine gems of different colours and 'grades' for different effects...(of course the bombs don't hurt either). Anyway, 5/5!
The phrase 'You can't teach an old dog new tricks' has officially been proved as bull****. You took, a great game (5 Differences...duh) and turned it into something even better. Of course, with the same artistic design. I look forward to seeing 7 Differences!
