I'm not very good at platformers haha
But I did like your art style and color palette. The sound design was quite charming. Your text was short, sweet, to the point and nice to read. My points of improvement for you is that the spring pads are easy to miss, and (this might just be me) but the first button wasn't working when I tried it the first few times. I had to refresh and try again before it worked. Otherwise, nice job! Keep going <3
