Hey I tested it and it is interesting, looks like a clicker game with upgrade mechanics! I liked to see the lawnmower get extra spicy with every upgrade. I found a bug in the Auto mower upgrade where if you keep on clicking after getting to the max level it -1 from there on the max value. 
In the end, the art is there and the concept is a good ground. It can be furtherly expanded into something else! Good job!
