Wow thank you for taking the time to give a very concise feedback!
Next time I'm going to join a jam that's during the week as that's when I have the most free time to really focus on it, I nearly gave up on this jam because I felt so demotivated in what I made in the time I could spare but pushed myself to finish and publish something. I felt that my game idea was good but I wished I had given its deserved time. After publishing though, I realized this was good for me and made me want to do more jams, so I could learn even more and hopefully become better.
I wonder if the collision bugs was a result of turning it into a webgl, when I was play testing within unity and the windows version I didn't have those issues but this is the second comment of it now and I can understand how that collision bug can really take away from the game. Next time I'll definitely spend more time trying to find bugs that would disrupt the flow.
Thank you on the tip of giving clear instructions or controls. I didn't even think of that but it makes so much sense and I will be doing from now on.
