I didn't actually think about the sub-pixel movement, that's a good catch. Thank you so much for the kind words though!
Regarding the popups, we actually had a lot of ideas for different popups, but you know how jams are! Maybe this is a project worth continuing?
The speed boost idea is really good and I can think of a couple of ways to implement that myself hehe.
We really do appreciate you stopping by and playing our game though, you really don't know the smile this put in our faces.
Thank you so much for playing!!!
