I'd love to see a sandbox mode for this game, where you can change lights/heat/drops(FA,AA,etc..)/virus invasions etc..
Or a multiplayer version, where you can produce your own 'viral rna' to attack the other cell(s) (like the toxins you produce on the final level), called "survival of the fittest"
With the magic squares puzzle, "medium" difficulty is actually the hardest, because the "easy" and "hard" levels are 3by3 or 5by5 (odd order), while the order of "medium" is even and a power of four. Puzzles with an even order are harder to solve than the odd ones (in fact, once you know how to solve the odd ones, you could make a square of 5001by5001, or any other, as long as the order is odd)
Oh, now I see, left mouse button increases your speed while it's hold, but also damages your health. You know, most games use a "stamina" system to limit sprint, that might be worth considering?..
To easily get the award for 100 seconds on x2 difficulty custom, use these parameters: Bullet Speed:3x ; Bullet damage:4x ; Bullet Spawn Rate:0.2x ; Triangle Speed:5x ; Good Powerup Rate:0.2x ; Bad Powerup rate: 5x
It'll take around 50 seconds before the triangle fires a single bullet, after 100 seconds it's like the first 10 seconds on normal. Vote up if helpful.
This could be a very nice game, were it not that the instructions are so damn unclear, (eg: in the first "secret" level, the instructions state something that could be interpreted as "maintain the reaction as long as possible" OR "hit 8 atoms" OR "click four times and gather 8 atoms")
Needs upgrades! And more enemies! and.. Just kidding, I'm glad Kongregate supports Unity now (if only because this means in-game cursors don't get all messed up if I press the right mouse button or switch tabs), and I can't wait to see some real games instead of demonstrations. Btw, I beat your demo on "insane" without losing any of my life!
