Extremely addictive!
I got to level 29 last time I played, but then I was so tired I started doing stupid mistakes.
The game is easy once you get the hang of it! Explosives are power! They damage without risk, so you can use them to get rid of the self-multiplying red dots very fast in the beginning of a level and by doing so refill your health bar. You can also use them to kill a lot of dots at once (especially in bonus levels) and obtain refills or multipliers. And as a last resort you can use them on the black dots. It will increase the difficulty of a level but also refill your health bar. If you run out of explosives you can get them from the blue dots. Control with the KEYBOARD always, it's much faster and won't render your wrist useless for the rest of your life. It's only a matter of training.
For the actual review: The graphics are as good as they have to be. Some flaws made me decide on a 9 instead of a 10. The sound loops are okay, except that they don't actually LOOP, which is a pity. Last time I tried the continue button, it sent me back to level 2. Since I was in level 25 when I lost, I wasn't very happy about that. There should be a high score system! I think there was something else, but I'm not recalling it right now :PAnyway, good job.
