Surprisingly sophisticated game considering the format. It’s really well polished, I can tell you spent time on this, it seems well thought out. The first source file I opened looked similar to Go (which I like!) and TIL about the Umka language, thanks! I My favourite thing to highlight from the game has got to be the awesome transition effect when time slows down.

Great game! I was trying to find a shoot button to destroy asteroids, a screen with controls would be useful. Awesome that you haven't made it in a standard game engine too!

I really like the colour switching with the slowdown mechanic!!

Some music would be nice as the game seems a bit quiet.

Well done man!

Actually quite fun. What I didn't like was the readability - it wasn't immediately obvious what was an obstacle and what was a powerup. Apart from that, I really liked the slow-down-time-shader, but I believe you played music over the sound effects, which is not allowed.
