Pretty simple game. What you have presented is a neat little strategy game. Unfortunately there is no strategy needed. All of the AI players move towards the ocean so it takes no more than 5 clicks to win the game but like you said you were unfamiliar with the tools you used.

The good thing is you have a core mechanic that works. All you just need to do is polish up the other elements and add some sounds, possibly some music and perhaps more levels if you wanted to go the strategy puzzle route or even just some different world configurations to challenge the player.

I have to say I really like the idea, and it works well. I hope you work on it more after the compo and flesh out the bits that need some work and add the polish that is needed. I'd like to play it again once you've done that. You can even add a post compo version to the game page.

Oh, since you have no sounds you may want to opt out of being judged in that category.
