So I read nothing before giving feedback. I just think a game should teach me everything I need to know but that's just me. Following is my stream of conscious:
- I like the hand draw art and the depth of field on the title screen. Do more of that dof effect
- What am i? a sheep with dynamite on his back?
- Sometimes I click and nothing happens, I'm expecting the sheep to jump when I click!
- why did I break the glass thing?
- Oh I'm supposed to click on them...You need to tell this to players explicitly.
- Eraser effect is cool
- Great job on the music
- Sound effects are good
- Great polish on this game
Now I hope you don't get upset with me but I think your game has a fundamental problem. It's just not that fun. I'm not trying to be mean it's just that the core mechanic of the game is to click on objects to help the sheep progress. You must choose when and what to click on. Really the game is about clicking an object at the right time, which is pretty boring.
It's obvious you have talent though. This game is well polished with music and effects and there's even a unique look to it. I just think you need to find a better core mechanic and you'll make some great stuff.
Okay now I'm reading your post...
Your sound effects are just fine

The game is edging toward the easy side but that might be because you did a great job with the death restart, it's very fluid.
