This is a really interesting idea for a game. After playing for quite some time I am not sure what victory even looks like in this game. It seems to be one of the types of games where you just continue on until you eventually lose, trying to get the highest score possible. I was unsure at first how to actually score in this game. I managed to survive quite some time without ever interacting with any of the balls. It was only after actually trying to use the left the click feature that I discovered how the score actually worked. A hurdle for me was definitely just not understanding how success was tracked in this game. After this the largest hurdle I faced while playing this game was simply the physical skill and the hardware issue. I imagine it would have been much easier with a mouse, but as I only had a laptop to play with using the left click feature on a trackpad was very difficult. It also seemed as though the balls moved much quicker than the player was able to. This made my original strategy of trying to just quickly react to the balls as they approached and make quick dodges much harder. I had to shift to trying to predict where the balls would land but eventually, the spawning of the balls became too much incorporating the left click feature seemed crucial to success in this game. The hardest thing to perceive was the hitbox for the balls and the timing of the left click.
