Great example of how a simple game can be interesting!
I love how you are using non square tile movement
The non-square movement ended up being both a blessing and a curse.
It gives a bit more definition to the lily pads ( with the subtle wobble when a frog lands on them ) but they take up quite a bit of room, so my original ideas for puzzle levels disappeared as I didn't have enough space to make them interesting I thought. Or I'd have needed to spend more time sorting out a camera system and all that entails.
