I intended to partake using GBDK too. ;) (Although things got in the way and I was too late.)
The game reminds me somewhat of The Lost Vikings in concept. In case you do not know it: you control three Vikings, each having specific abilities, and must bring all three of them to the exit alive (and also with a key or something akin, in the last levels of the worlds).
Takeaway: The game feels complete as a little demo, ranging from cute characters to the music; I can easily see it extended into a bigger game by having more varied enemies (with different behavioural patterns) and mechanics (switches and so on). The concept of having to switch between several characters is a classic, actually (see the example above; also seen this concept in game jams, I am thinking of NeededTwo or Cubemunity, just to mention two of them), but maybe a specific feature of yours would be to have each level fit in a screen without scrolling, as is now the case? So that you can always watch everything easily. It could give a more ‘puzzle’-oriented feel to the game compared to others. :)
Thanks for the game; motivates me to finish my own GBDK-one! :)
Bugs / Suggestions:
- First time in first level: both pirates were at their respective chests, but had some trouble validating.
- Possible bug: pressing a button from the Game Over screen seems to also skip some further screen(s)? Merely had time to catch a glimpse! :o
- A counter for the number of lives would be a nice little help!
- I think I beat the game! Ah, brings me back to the first level; I think a little victory screen instead would have given a fuller feeling of closure. ;)
