Thank you for your feedback!
The game was intended for mobile play ;), and I knew I'd like to work more on it and one day release it :).
Yes I couldn't implement the potion throw as well as I wished so that it's less confusing. It should be more clear what is going on.
So maybe show a "ghost" throw, which represent what will happen, and maybe the potion should be thrown and explode while in pause mode too. Maybe the jump/fall should be slower?
Not sure exactly how to make everything really clear to the player. But I'll have to because I'd like to add some more different potion effects, obstacles and enemies :).
Thanks again!
