If I could give this game 10 stars I would. I've owned this game for over a year and it is one of my ol'faithful games that I go back to time after time. I wish I knew how many hours I've spent enjoying this game. My grandson (6) used to play all the time. we go in streaks as to what our favorite game of the month. I had not played Tutrix in a long time & when I saw it come up on the $2.99 deal I went back & played a level. I managed to get thru level 3-10 on hard & had to try twice. I like that kind of challenge. I find the controls to be just fine. I use the mouse 99% of the time. There are a couple of tricky spots where I find I need the arrow keys for best control. It does require considerable skill to be good. I love going throught the levels with the darling little turtle. I never tire of the cute little voice saying "thank you". A much better game than Trutix 2.
