Gem Jumble

Click a gem, then a neighbour to swap (or drag from one to the other). On a keyboard, move the frame with the arrows or WASD, press Space to pick a gem up, then an arrow to swap it that way. Line up 3+ of a kind. A match next to a frozen critter cracks its ice; crack it through and the critter is free. Free them all to clear the stage and top up the sand. Match 4 for a Glimmer gem that zaps its row and column, match 5 for a Prism orb: swap it with any gem to clear that colour. Freed critters leave Slow Sand bubbles; click one (or press 1) to slow the clock. Stage 4 is Old Frostjaw, who freezes your gems until you smash him with matches. When he breathes in, the two gems glowing blue are his next targets: match them away first.

A paid run pays by medal: bronze 65 Glimmers, silver 140 Glimmers, gold 250 Glimmers, with a small token (up to 20 Glimmers) for no medal and 40 Glimmers extra for a new personal best. It costs your Glimling 1 energy.
