A bit of an odd but interesting platformer.
I greatly enjoyed the time rift ability, and the graphics were great, I loved the Powerpuff style Kronii.
The jump physics were a bit odd at times, which made maneuvering a bit awkward. In addition, maybe this is just a local problem, but audio would stutter a lot for me.
Honestly, the fact you needed two playthroughs; one to gather all Kronies, and one speedrun was very unclear to me. My recommendation would be to simply remove Kronies the player has already gathered on subsequent loops. That way, going faster makes sense and would feel natural.
(In addition, if you do the speedrun first, Dark Kronii still tells you to go Faster, instead of telling you to gather all Kronies.)
