Hey, I played this game. Here's what I think:
~RTP Graphics. A definate no-no. However, being a test game, it's okay. But in the future, try not to use the default charsets and chipsets.
~Map design was not the best. Not much freedom to explore, and it was very linear.
~Not very creative use of the DBS. But why fix what's not broken? No complaints here.
~Overall okay... good for a first test game :)
