The tutorial is a bit too fast, in general I'd say it's better to let the player control when it moves on if there's reading involved. I also found the infinite jelly bug, which was fun but takes a bit of the challenge out of it :P It might not be an issue if you're only supposed to get a handful of jellies each round but it would be nice to have an option to hand over all jellies of a given type (or at least bigger increments like +10) to avoid tedious clicking.
Overall though it's a fun game, well done :)
