Hi Mateusz,
Thanks for this feedback. I'm sorry to hear that you've been unlucky enough to have a bunch of different problems that nobody else has reported - I can see why that would be frustrating for you!
Because the game was so short, the decision was made to not include a save/load system. I'll think about putting in unlockable chapters instead.
I am considering releasing an update in the next few days, which may address some of your issues. For example, there is supposed to be a fix in place that stops the ball from being pushed behind Bonbon - I'll need to check if this is working. The rubber rings can also sometimes bounce away from the box after they have been counted - I'll look into that too.
As for the other things you mentioned (the game not advancing after the rings or cake), I can't imagine what is causing those. Please can you tell me a few things: which version of Bonbon do you have? It should be v1.0.2, but do you have the 32bit or 64bit version? Can you also tell me your system specs, including your graphics card, RAM, CPU and Windows version. Please can you also let me know how the game runs generally - is it smooth/jerky, does it take long to load, is there texture pop-in? Thanks!
Cheers,
