There is a suspicious blue rabbit with a violet egg ...

This one is cruel. The blinds changing without any indication they've done so was my biggest bugbear. Click-and-dragging the stool would be number 2 (mainly because dragging in a escape game is not a usual technique).

There's a couple of puzzles you need a screenshot for (eg Chicken triangles). I applaud the coins showing both sides in the inventory though.

I liked the combination puzzles. I easily got the shape/colour/number one but missed the shape/coin/letter one.

Bunny paw puzzle put me off. I thought it'd be for the bunny.
As for the bunny, it didn't seem to have the egg locked up in any way but after I cleared the above puzzle, it was obvious what to do.

I can't detract points for me missing clues but I can for the oddities. This one didn't have tooltips but the graphics were clear enough not to need them. A decent game that misses the mark of perfection for me.
