You get to the winter games levels by beating Level 15 in normal mode, then open the Galactic Map from he pause menu and click on the arrow leading off the main path. Mouseover text should say "Winter Games, part 1"
Agree with ChaoticBrain. The flow would be much improved by removing many early levels (2,3,4,6,7,8,10,11), and adding more later levels. Apart from that, this is a beautiful clean implementation of a puzzle game with some classical and some innovative mechanics. Well done, 4/5
To get the badge if you've already completed the game, Redo last level then *press play button* to get the "Well Done" screen. Badge won't award if you click back to level select instead of continuing.
Excellent concept, competently executed. Key controls would make it even more playable. Please. Make Z, D, W, Up, and Right keys all increase the selected counters, and A, Q, S, Down, and Left keys all decrease them.
Going through old badges, I'd missed this one. The flash of the start for the *next* number to hit is actually pretty offputting when you're on a smooth run, because it feels like your mouse is ahead of the cursor.
