Pros
Pro Polished presentation
Quell+ takes the extra step to have a very polished presentation. First there are no loading screen, so all menus and levels move along smoothly and have zero wait times in any transition. Second is that there is a very artistic design around each level where in a user navigates menus that are presented as a story one must reveal. The overworld is presented as a bookshelf that contains different years as shelves, each shelf has a selection of levels that have an certain theme, changing with each year selected. Overall it is a unique representation that shows a lot of polish over other casual puzzle games.
Pro Superb level design
Though the basis of the game is simple enough, collect all fragments in a level with as little moves as possible, there is quite a bit of good level design that uses a few different elements to make the gameplay challenging. Things like being able to teleport across the board or blocks that appear to block your path once passed over make each level more challenging than the last due to smart level design.
