by shimmier hanging under the bridge

First, the two workers must meet on the lower floor and build a bridge together. After that, one of them should go back upstairs to complete his own task.

Digging through the splat zone to allow the top lemming to fall safely is actually necessary. However, the lemming who digs through the thin floor must not end up on the bottom level, which means you have to prevent him from falling by assigning a builder. But how does he survive the fall after he finishes building? That's where the bridge that the two workers build together comes into play.

Unfortunately your solution is a backroute. You're right that I'm trying to force the player to use both exits though. It's required by the rule! 

Lems Are Playing Freeze Tag – I hoped this level would help you get used to the slider mechanic for the upcoming more difficult slider level.(Watch your step... )

Lighter Than a Snowflake – Looking back now this level might be a bit too difficult for where it is placed. I've received similar feedback from several people.

23:58:30 12/24 – The idea behind this level was: can you make a level with a single hatch and n exits, with a time limit that only allows a solution if you go for all n exits? The answer turned out to be a relatively easy "yes".

Lost and Found – I wanted to give some spotlight to one of the least-used skills: the stoner. You can create terrain mid-air without any starting point for constructive skills and that's a unique feature of the stoner!

Claustrophobia 2 – A spiritual successor to my level Claustrophobia from the previous Xmas pack. The urgency created by the tight timer is completely intentional!

Happy New Year! – Just for your information, several levels were co-authored. The general rule is: the first author listed creates the terrain/objects and the second author creates the solution.

Living in a Fairy Tale – This is my favorite tileset.

The Bear Necessities – Not exactly intended, but your solution is actually better than my original one!

Walking Bearfoot in the Snow – Yes, I didn't want to add too many extra elements beyond the main idea of the sacrificial jumper.

Sky Shield – I think you could have solved this level even without the hints!

Watch Your Step! – The theme I had in mind was that all skills must be provided as pickups similar to rule #3 in the current level design contest.

Warm Cozy Basement – I'm glad you liked this one. It's my personal favorite level in the pack!

Constructus Interruptus – Yes, this level stands out a bit in terms of difficulty. I could have removed some tricks to make it easier but ultimately I ended up liking them too much and kept everything as-is.

Where Angels Dare – Yes, this one is more of a visual level. I drew the scenery first and the solution came afterward!

And They Lived Happily Ever After – If this level made you laugh, then it achieved exactly what it was meant to do.   I didn't have any particular reference in mind when choosing the title.
