Turned out that it is much easier if you heat them from the start while they are swarming at the centre. I love the idea that developer is basing this game on. Make it so relaxing. It is quite smart, and I enjoy recruiting other entities to join my course :) and the Black and Red choice is really nice. Would love it more if there is a stronger sound effect when player heats the flows. I'm not sure if I need to heat more flows or if i faced a glitch coz I've been rolating for a while with the flows but no door is opening.
Anyway, Cool Game umbra_onovich :)
