Castle Craft on Scirra arcade

I have created my first game and uploaded it to Scirra arcade, it is called Castle Craft and you can find it here: https://www.scirra.com/arcade/action-games/castle-craft-1879

It is a first attempt at a game creation so any review/feedback will be greatly appreciated and I hope you enjoy it.

In the game you must build your defences, and gather projectiles to take down your enemies. Win games and collect stars to unlock more and stronger defences to give you the advantage in the fight.

All controls are touch (drag/drop/swipe) so it does work on tablets as well as desktop.

I look forward to hearing your feedback,

Thank you.

I see potential for a multiplayer game. I think you also should add some crazy characters like in Angry Birds or so to give the game a better profile. Apart from this it's good so far.

Thank you for your feedback, I haven't quite got myself around how multiplayer works yet but yes I will add more characters and better building blocks than just shapes.
