Congrats on your first jam! I really like the way the theme has been used as carnival game with the cost of tickets to unlock more buttons and items as well as the challenge of trying not to waste balls. I really like the edition of the collectables! really adds to the feel of it being a carnival game as well as the ticket multipliers they gave you, that's a nice touch!
the cross hair confused me a little a first though, but I understood it as I played through and think it was quite a good idea for judging the height of my throw!
would've been nice to have some music and sound to add to the experience though.
Overall Good effort, Well Done! : )
