The design is very boring since it's mainly, indeed, linear. All the levels are a "from left to right with some enemies spawned here and there" pretty much. There were no real challenges, no interesting sections (even if some ideas weren't bad) and overall very boring. I hated the level with the brick blocks idea, since it was very confusing aside from not being suitable for a world 1 level in terms of difficulty.
Aesthetic-wise it's kind of messy. Some levels were okay, but some others either felt too empty, or too messy, or clashy with the style of the hack. The author used redrawn style + YI graphics + SMAS graphics mostly. It feels indeed just a big mess, not very pleasing.
- There are problems related to music in this hack.
- If there is a dynamic sprite on screen, the top screen may flash black for a few scalines.
Overall, not a very interesting hack. The hack itself is also pretty short, so I wouldn't recommend for those looking for a good one.
