Nice to see another word game with a different take! I really enjoyed it!
At first I was confused about the actual mechanics, but it shortly became clear that gaps don't matter and your best word is saved, although you may want to communicate that more clearly?
I'd also strongly suggest to add a restart button as a good run depends on a good starting word
Oh and the game runs in the background, so I can cheat and get endless time :P
Highscore without cheating: 43
