Absolutely loved this game! I didn't get very far, but I was just grinning the whole time! What a delight!
Like some others have said, the spacebar to start wasn't something I immediately noticed, but I must have just been keymashing enough that I hit it anyway. I think making it just a rectangle rather than an oval shape would make it read more spacebar and less UI.
Didn't get far enough to figure out what was going on with the paddle looking UI thing on the right that was making a shape. I thiiiink it was going to eventually make a full shape upon winning or getting far enough? But I wasn't too worried about it cause the experience was so fun!
Loved the sound effects and the music ramping up :D Wonderful little game!
