Adding enemies (besides they are inactive ¬¬), rings (where's the ring loss?), yeah, it's an improvement, but I didn't said that how was the improvement.
Just this!
The Boost Factory act 1's level design is fairly good, but it's still empty, there are not power-ups, more enemies, traps, and some details. Please, fix this and don't make each cutscene's talking in different rooms ok?
