Other games like this for 3-5 years old?

Are the achievements broken? I played through the 6 levels and haven't unlocked any.

My kid loves this game. Are there similar games who don't punish kids too much and allow them to get comfortable with controls and enjoying.

My kids both love this game, but the arrows and controller are a bit too difficult. They are comfortable clicking, though. Any chance of adding click-to-move so they can move with the mouse?

On the 5th map (I think) where you first can change color, there is a pumpkin hidden behind a tree near the castle. In 90-degree mode, you can't see it. My son and I ran around for ages trying to find it, and only found it when switching to 45-degree mode. Might be worth shifting the pumpkin to make it more obvious....
