only 10 letters holding space, and some of the words are nearly 10 letters long
(Painting for example.)
So you sit there waiting for the missing letter to show up while time runs out.
Even short words, like bed, can be impossible to complete quickly.
This game would be frustrating enough without the time limits on the level being so short.
Best strategy would be to get the longest words first, then do multiple short words when you're near the end.
