Multiple deployments in a game is really interesting choice. If I understood rules correctly, I like how it kind of simulates multiple days of siege, where armies clash out at dawn and retreat to their camps by night, only to renew their assault next day.
I like that you were able to squeeze whole game in single page and your game definitely follows the theme. I haven't actually played this, but seems like things can quickly start to escalate out of intruders control.
Here is that part. Now that I think of it, it might have more to do with that plant that is on front of the wall, giving impression that it belongs to background.
Ps. I've found myself booting up this game just to listen to that catchy music that plays most of the time.
Neat idea and execution. Hope that there will be more.
I think that "ground" tiles should be more clearly separate from "background" tiles. At least once I thought that I can make a jump and was blocked by something I thought that would belong into background. Also I think that some challenges are too precise. A little bit of leeway would make it flow smoother.
In all other ways I think that level design is just right. I always had some kind of clue where to move next, even without any instructions. Challenges were fun and it is nice that new mechanics emerge through different creatures that have their own purpose (love how snails work as shortcuts for cleared challenges). Music is awesome.
I had some performance issues on browser, which I guess is to be expected.
