Quite impressive!
I'm not a fan of RPG's, but this was very well done! It was a bit annoying how those green blobs fired at you and the boss was hard, but at least you were able to switch levels whenever you wanted, which really saved it. The powerups were also interesting. I thought the graphics were very nicely done, especially with the houses. I can't really understand what your companion is supposed to do, as she just seems to get hurt a lot, but overall, a very nice way to waste time.
