Things I found:
Weapon aim resets to north when the right stick is released.

Lighting needs to be rebuilt.

Months ago, I did a complete rip of this pack into SMBX, which took me quite a significant effort to rip.

its like making a game revolving around the big boo battles of super mario world, which use blocks in the terrain.

really like the character designs

aamatniekss, shikaternia, vnitti

third party sources used?

the airship in the intro cutscene has supersledgebro's smb1 airship tileset converted to 8-bit

the water looks suspiciously like mario graphics.

The snake and vulture enemies' AI can be exploited for easy jump kills. The vultures can be jumped on and they can be jumped on over and over again as their attack is not effective when the player is above them.
