Hi there. Hope you guys are well.
Well done on the game, I think it looks great and is a solid concept.
I have some feedback I'd like to share if you decide to further develop it.
First thing is that I think you should switch the colours of Dragons' and Sheep' health, as the red on the sheep made me think I needed to shoot them first. It is mostly just a universal translation in games of Red means bad and Green means Good. (that's just me however) I also felt the collision on the Projectiles didn't always hit my target and passed through, but that is fine since you made this in a weekend and I assume not a lot of time for testing.
I hope you guys consider working on this further, maybe releasing both a WebGL and Android version.
I look forward to seeing your future projects. Well done!
