Great concept, and lovely presentation! Kinda weird gameplay. I understand that the "meteorite" changes colour according to what it wants, but giving it what it wants seems to explode it anyway sometimes? I think the main problem is that I can't distinguish the colours well enough. Seems like a few different channels of communication would work well. It's quite expressive as a character, you could have augmented the colour messages with what it does with its eyes, how fast it's shaking, is it pulsing vertically, shrinking and growing...
I never got to the end of the time limit without blowing it up by accident at first. I realise that's just to satisfy the theme, but I'd still have appreciated an option to turn it off. I dislike being arbitrarily put under time pressure. It stops my critical thinking and makes me panic the first few times! Only on my third run did I actually examine the environment for clues.
Also, for us old guys, we'd appreciate an option to invert the mouse controls for look up/down. When I first started FPS gaming in the mid 90's, the norm was completely opposite to what it is today. I spent half of my time in your game looking straight up or straight down! I mean, you have a settings menu, and it's just an "if (inverted) look the opposite way", right?
I hope I haven't over-criticised above. I actually rated you very highly, despite my niggles. I'm hugely impressed at what you've achieved in just 4 days...
