I want to start by saying how cool this is for an RPG Maker game, loading into the first level and seeing the 3D environment was awesome! The gameplay is so fresh for the program and a breath of fresh air! The art is also amazing, seriously great job on the character art as it is extremely well done (If you have social I'd love to follow)!
The gameplay does have some issues, particularly with the angle of perspective. It makes navigation difficult, particular cases are the vertical environments and levels with a LOT of similar tiles on the floor and gaps the navigate over. Level 2 is the biggest example of this as both section one and two are extremely hard to navigate.
The ranking and score system could be improved in my opinion as too many mistakes completely nullifies a run. I'd personally try a "star" like system. Completing the level with no deaths and under certain time requirements earn you bonus dream orbs while while orb collecting can remain the same as the main goal rather then a multiplier. But that said, adding a quick level reset button could help lighten frustrations with the current system if that is preferred!
Overall an amazing game still, I hope I don't come off as too negative or critical as genuinely I see so much potential here and would love to see more! I highly encourage developing this project more, and if possible explore making it in another engine as I'd love to see even more expression for you outside of RPG Maker!
