Tip: You can use Lunar Magic's Overworld Layer 3 Editing system to edit or create your own layer 3 images (castle bricks, fish, rocks) and apply unique effects per level via the Layer 3 Bypass in the main editor.
Yes I know it's a very vanilla hack, but I've planned to make a more advanced hack one day, this hack was mostly a test of Lunar Magic. Despite everything, I've tried to make it fun to play even if it lacks the creative potential that longer and advanced hacks can bring.
Anyway thank you for your comment, and stay tuned ! ;)
I played through the entire hack and all secret exits. The hack itself feels very amateur; as if you are new to Lunar Magic and are in awe of the capabilities of modification in this nostalgic Mario title. We've all been there. This hack meets all the minimum requirements, and I can't say in any capacity that it's a bad hack, but speaking honestly, I feel there is a lot of learning and experience to be had in order to create much more polished products. Keep hacking and don't be afraid to experiment with the other assets available such as custom graphics, sprites, blocks, and music.
