Your hack is very interesting, every level introduces a unique and fun concept. ASM hacks are used in a clever way, and graphics are colorful and fun.
Difficulty is well-balanced and the game can totally be beaten without using savestates. Thank you for putting a save point on the overworld, very useful (and so counts for the well-balanced difficulty).
10/10 (5 stars) Had a very good time, thank you =]
"HACK" is awesome! It's really fun and its gimmicks are interesting. Also, great YY-CHR on the Title Screen. However, I don't like the level in which you must collect the coins and they run out every second (even during the power-up transformation)!
