Well, I will give you credit. At least it's playable and it's better than a chocobreak game or a very crappy platformer. Still though it could use some refining. First off is the graphics. Now they're basic, which is alright, but you should have been able to create your own diamonds instead of resorting to the default image used for active object. Next is sound, or lack there of. I know there are issues with TGF2 and sound since the files can take up so much space, but even a basic tune or some sound effects would spice things up. Finally are the enemies. It might be just a gripe from me, but the enemies move too fast (either that or the protagonist does) and the hit detection is awful. I didn't even touch him and I had to restart. What I would suggest for here is a possible health system or a rework of the enemies and/or speed.
You have potential. For at least being something that could be considered a game and for at least being unique compared to some other TGF2 games that people try to pass through, you get 2 stars from me. Do hope to see more from you.
