Nice game, I have a couple of suggestions:
- The physics feel a little weird, the big shoots up super fast, then hits an imaginary ceiling, hangs in the air for a long time, then falls down really fast again. It might need some tweaking
- There's no feedback for the player when you're ready to shoot again. I found myself waiting for the bird to come back into the slingshot, before I realized I have to click to put him there
- I like the artistic style of the birds, pigs, and background, but the platforms don't really match and look a little bland
- There were quite a few times I hit a pig dead on, and it didn't disappear. Maybe this is a bug, or maybe you intended them only to die when you hit them a certain way? Either way I was confused a bunch of times why they weren't dying
Overall a good game, especially for being made in only one day
