Yeah - no worries!
It is a shame the tech was (and has become more) difficult to maintain :(
I dont think that last issue is related to the controls one.
All Shockwave games occasionally run out of all kinds of memory. This can happen faster on some machines with some of the advanced, experimental features on. It is old tech and harder to maintain, which is odd since machines got more powerful :(
About the controls issue - I am out of ideas. I tried on multiple machines with and without controllers, but I could not reproduce.
If it wont work you can apply for a refund through https://itch.io/support Sorry for the inconvenience.

That should be more then enough. Mayb e it is the resolution and/or settings?
Do you have any of the advanced settings on? While your system should be able to have them on maybe there is some sort of conflict? The advanced settings as well as high resolutions aren't very well supported due to engine limitations. So these are a bit experimental.
Best thing you can do is to use the itch app.

With the app you can install & update the games as you would do in e.g. Steam as well. Savegames should stay
