Hello!
I'm sorry you're having trouble with the controls. I'll investigate this and see where this bug may be coming from. Thanks for you feedback!
One thing I noticed is when you run into a wall or object, at least for me, it makes it to where the first time I press left click after I interact with the wall or object it does not do anything. I have to press left click twice after that. But, that wasn't the only time the issue arrived. I really wanted to play and it seems like the platforming part shouldn't be that difficult. I don't see anyone else talking about it so maybe it's an issue on my end. Hopefully some other people chime in. And thank you I appreciate it!
