Most of my critiques about the game have already been mentioned by other people, and since you already plan on fixing these issues, I don't think rambling more about them is necessary. 🤔
That being said, some positive feedback never hurt anybody!
I really love the overall presentation—the way the game takes place in a single scrollable scene, how the different screens are organically connected, the animation of the blocks being created and destroyed, and obviously, the art of the slime girl! She's really cute, and her small movements and expressions give her a lot of life.
The lack of sound is really a shame because otherwise, the game feels really polished.
Gameplay-wise, I don’t usually enjoy clicker games, but this one didn’t feel like one, even if it’s quite simple. Using the horizontal strike and the dynamite kept me engaged until I unlocked every upgrade. Good stuff!
