I love the concept of the game. I really enjoy golf games so I loved this game as a whole. The armadillo is very cute and the graphics look fantastic. I read the problem of the game and the size of the screen so I guess you are already solving that. I found the camera controlls (mouse) very hard to really get the right angle so I would try to make it smoother or something like that.
The 3 levels were short but you can see the potencial that this game has to offer. I had a blast throwing the ball around in the third level. However, it's hard to notice the rewind mechanic because you would normally get in time to the ball before it runs out of movement.
I found a bug that if you pick up the ball when is starting to rewind it gets stuck and it doesnt move anymore (but you can cheese the levels picking up the ball and rotating to change the position).
Overall, a very nice game. I really enjoyed it and I hope you had a great time making it.
