Giggs, you're a god. Legit, this is so amazing. You set the tone perfectly from the opening cutscene which was off the wall hilarious and so so well made. The pixel art was incredible.
You've managed to grab the best thing about Peggle and distill it into a game: getting that fresh board. When you start a new Peggle board and you're just slamming around hitting a million pegs, it's so juicy and fun, and you have replicated that here insanely well. The way the camera shakes and you hear the SFX when you hit a peg? Sublime. And then the way the camera continues to shake at high combo numbers? Such a good idea, it feels so good. This game is an absolute joy to play. You've quite simply nailed the concept.
I love the way you don't penalize the player for getting a red square, either. (Do you? I couldn't tell) Because you get funny text about poop and butts and that's a reward in itself. One complaint I would have about that is that the text you fill in isn't called out very well. As I was playing, I would glance to the right to see what word was filled in, and I often had to re-read the whole text because I couldn't always remember where the blank was. I think it might be better to color the "user filled" words differently on the right so they catch the eye a bit more. You could even have them be light red for "bad words" and light green for "good words".
I was confused by coins for 80% of the game, but then I figured out you could buy balls with them so I spent all my money.. Right before the last gate where I found you needed 100. Oof.
Last fight was incredible, you could make a full game about that. Puzzle Quest-esque if you ever played that.
