Thank you for such detailed feedback, I'm really glad you enjoyed it.

I think you're right about the spread of the collectables - sometimes it does place them quite close together, I'll make a note see if I can improve it. I totally agree about the space bar mashing being a bit at odds with the rest of the experience will have to think on how to improve that!

The occasional floating islands are a result of the way I chose to do the generation, but I like them too! So didn't seek to remove them.

Also I like your avatar image.
