I only have one thing to say to this! D: It's not MV/Z3D, it's using the rose engine, my own personal 3D renderer( available on my itch.io page ), which was built from scratch! It's quite a bit more flexible than MV/Z3D :D The 3D platformer bit is just a preview of what's coming for the rose engine soon enough, like you said though it's incomplete, there's quite a bit of work that still needs to be done.
Thanks for the rest of the review though! It was fair the game was rushed, i spent the only the last two weeks of the jam working on this game lol. The battle system was shoehorned in from cyanima, but as I was so short on time I didn't have time to fix all the errors that occured migrating the engine from MV to MZ, also I didn't have time to flesh out the battle system either ^^; Im sure the game could have been better if i focused on one aspect lol, but this was just for fun, and advertisement for my 3D renderer honestly.
