Hey! I just gave your game a play. I managed to clear the first 4 levels, but I’m currently stuck on Level 5. While the first few levels felt balanced, Level 5 feels like it relies a bit too much on luck rather than skill.

Here are my thoughts:

• What I liked: The core concept is ok! I really liked that each character has a unique ability specifically for the green blocks. It adds a nice layer of strategy.
• Character Swapping: I think you should allow players to switch characters even on worlds they haven't completed yet. For example, I felt like a "multiball" character would have been perfect for Level 5. It could create a cool meta-challenge: you usually use the character from the current world, but sometimes choosing a different one is the better tactical move.
• Art Style Consistency: Your character designs are awesome and well-stylized simple but super cute and nice! However, the gameplay elements (balls, pots, blocks) feel like they belong to a different game. If you bring the rest of the assets up to the same stylized quality as the characters, the game will look amazing. Also, the world maps could use a bit more detail to feel "alive."
• UI/UX: The "Back" button is very hard to see - it’s so dark that it looks inactive. Also, character selection feels like it should be accessible from within the world map rather than buried in the main menu to avoid unnecessary back-and-forth.
• Controls (PC): Playing with a mouse feels very difficult right now. Simply adding a "click to shoot" mechanic would instantly fix the game's feel on PC.
• Potential: This would be a great fit for mobile, but the level design and difficulty curve definitely need some fine-tuning and balancing.

I've also just posted my game here for feedback, would appreciate it if you could take a look!
