Ok, I actually put it on my flash cart to try it out (don't worry, I'll buy it soon enough!!). ar as I can tell. So far it seems nice but the lack of the weapon combination system is kind of disappointing. The level design is a little flat compared with the original (so far), as well. Still a worthy purchase, but it doesn't quite top Astro Boy as Treasure's best on the GBA, unless it picks up quite a bit in the later levels.
