Simple, but fun! That third hand right at the start got me like 5 times... sneaky... :)
Having the timer count down instead of up is very clever to keep people playing.
The font threw me off a bit, I didn't realize that the timer was 1:30 since I couldn't read the 1m. Sometimes the hit detection feels a little heavyhanded (pun not intended). But, small gripes, overall, nice work. :D
