Heya! Thanks for playing. I'm glad you had fun with it :)
I agree that the effects of the pegs are really kinda pointless right now since you just pile them all on. The original intention was that some were riskier choices than others and you had to choose whether to go with high-scoring pegs that broke easily or low scoring pegs with a lot of durability.
> Something that I think can be improved is that it would be nice to see the durability of each peg without hovering the mouse on it
That's in the game already in the settings menu! :)
> I think a projectile preview curve would also help decide how to flick the cookie
I agree with that, I just couldn't figure out the maths to be accurate enough during the jam. I definitely want to go back and make that preview more accurate.
