I have just one suggestion. Put of the controls text in the same area. Having them so far apart is confusing. I didn't know what to do at first until I realized you could click the platform then I saw the controls on opposite sides of the screen.
Other than that I like the overall gameplay. It's simple but entertaining. I found my self playing longer than I intended too. The platforming is tight but doesn't feel too hard. I made it the edge just barely most of the time but I didn't spend too long on one puzzle either. I only about the first ten or so but I like what I see so far. You could do a lot with this.
The graphics are okay. They get the point across and you know what each object is. For a game this small in scope I think it's perfect. The only thing I found a little off putting about the visuals is you seem to have a fish eye type effect around the edges of the screen. I thought this was a distracting.
