I think this is great!!
I've never played a jump style game before. I'm not very good at it and I don't like the rage feeling. But, it would be really unfair to say this is your doing since this is what the genre is! I think for what it is, it's really well made. Well done, especially for a solo dev.
I like the art style, music, sound effects, and just generally how polished it feels! The purring noise as you charge the jump is brilliant, and the cling animation on that lamp shade is really cool!
