The concept and idea for this game is brilliant, but the execution leaves a lot to be desired. It seems that hitting the music notes will resume the melody, and missing it will pause the melody instead of having each note representing the melody; this is unacceptable. There are a few notes which I observe to be on beat, but a lot of the other notes have almost nothing to do with the music. For the first level, Melody autojumps to the beat and this is excellent design which I’ll come back to later, but in the 2nd level, she’s not on beat. In order for Compose to be a rhythm game, it needs to map the player’s actions to the beat, which it does very poorly. Basically, at its current state, it is like Temple Run, where the goal is just to collect the notes as they drop.
For this game to truly shine, the rhythm part needs to be more refined. Currently, the player hits the beat by jumping into the notes, which means there is no impact and it happens on the off-beat of action, i.e. the player presses a direction key, waits, and then only the beat hits. Instead of moving into notes, perhaps turning the notes into platforms/trampolines that the player has to hit/land on beat will tie the rhythm to the player’s action better. The existing trampolines/teleporters can still be there to aid with movement (i.e. to get to far away notes, get around obstacles, or make bigger impact landings when the beat drops for example).
I feel that Melody’s autojump is the key to Compose’s fundamental design. It is excellent that this is implemented. Therefore, most importantly, Melody needs to appropriately speed up or slow down depending on the music. How fast she autojumps should tie into the gameplay - and with the suggested idea above, it is crucial for the player to make Melody land at the right note at the right time because of the autojump. This includes big jumps with trampolines, which will stagger the rhythm, but it must still all be in the same tempo, and then it must sync up after. When you achieve this, you’ll have a unique platformer-rhythm game.
Overall, Compose has a lot of potential, but needs a number of structural changes and development for it to excel. Though as it stands, it is still a creative, cute and decent game. Keep it up!
