Neat concept. Reminds of Dave the Diver. There's potential here if you'd be willing to explore it! I unfortunately hit an annoying issue though where hitting spacebar just bumped my browser's scrollbar downwards, and despite doing everything I could, I couldn't get it to activate the shop, especially since you hadn't enabled full screen. I won't let that affect my rating though as I can see others below didn't run into this so it was probably on my end. Overall good job :)
