Great game! Needs some more game modes, the whole thing plays more like one long tutorial, needs some freeplay/survival kind of modes, perhaps a leveling system where you make your cell stronger between virus waves.
150 fireflies achievement was fukcing BRUTAL to get. I had like 50 runs with 149 of them. I better NOT have to do this again for some stupid "IMPOSSIBLE" badge.
took a while but I finally got it, all brilliant.

The trick is to max fireball and your mana pool early, fireball is the only way to kill some of the Ninja bosses before they reach your gems.
