Honestly, what is the point of heroes? They're not cheap to place, take a while to get in the first place and by the time you have the money to place them on a map all the creatures are so strong they're worthless. They're just too hard to level up to be effective....
It would have been better if the chance of getting a weapons power-up was a little higher. If you aren't lucky enough to get a laser power-up you get hit and end up with a rubbish weapon after being hit twice. Also, the shrinking-box thing is a bit stupid. If there's a lot of enemies you will get hit, regardless of what gun you have. Then the box expands and you lose a gun level....
2/5. No score-keeping thing, no sound, rather sharp contrast of colours - it's not even as if it's a particularly brilliant combination - and you copied a pacman ghost image from somewhere for your food. RIGHT. >_>
I find it boring but Sonny isn't my idea of entertainment. I think general destruction and death in games is more fun than long slow battles . This just takes too long. Why should we spend five minutes on every single tiny battle? O_o
It's not hard on easy, just unspeakably boring. The worst flaw with that difficulty is hitting anything going up or down. Chances are they'll be far above or below where you're aiming if you fire quite a bit in the direction they're heading. They also tend to change direction mid-descent or mid-ascent. That's not making them any easier to hit.
