The visual is very nice, I really like the partical effects.
The game progress is a bit too slow but the gamplay is nice, I like how you need to click the bouncing ball to get reward from it, and not just clicking the same spot all the time.
It would be better if the upgrade are more clear and easy to understand and not just guessing what does what, but still it is a nice system.
However, the lack of sound really makes this feel like something is missing, really wish it could have some music or even just some sound sound effect.
But overall, nice game!
