I finally managed to play Malaika a bit more! So now I can make more specific comments
First of all, there are two things I'd like to say. First, in spite of the "things that I don't like", Malaika is a more than decent entry for the MSXDev. I decided not to vote it because of the tech problems that were patched past the deadline and because of some of the playability issues that I'm going to mention later. Without the technical issue, I think I would have given it 1 point and without the playability issues, it could have been one of my favourites. Second... I have nothing personal with Malaika. I feel I have to say that, because sometimes in the forums things go personal when they should not. I'm simply writing about it because platformers are one of my favourite game genres.
So, let's begin. One of the most evident problems is that due to their behavior, enemies tend to concentrate on the same place. Of course not always, but almost. In the first screens this is more than evident, especially in the screen with "RELEVO" written on top. In that screen, just to put an example, very soon all enemies concentrate on the same platform leading to a lot of flickering. But flickering is not actually a problem. The problem is of playability: when this happens, winning does not depend on strategy or ability or being fast, it only depends on luck. The only way to go through many of the screens is trial and error.
In general, the game depends too much on luck, on the "unfair" kind of difficulty. Thus, the game is "easy" because of the continues. Without them, it becomes almost unplayable because it leaved me with the feeling that winning or losing was outside my hands. Slightly improving the level design and the enemy AI would greatly improve the game playability, that's my opinion.
On the technical side, I found some flaws, not as important as the playability one. Also, I think you may be able to solve them easily. First, do the game speed increases as you kill enemies to make it more difficult? Or is it a problem of the engine? Second, about the sprite flickering. In a game with so many cases with too much enemies on a row, flickering should be exceptionally good. And it is not... I am not an expert on this issue, but I remember some threads here and in MRC about good ways of doing flikering. Finally, not sure about that but... are there some collision-detection problems? or it was that sometimes I don't know who hit me due to sprite flickering?
So... that's it. Nice Dev entry, for sure!
