Today two side-scroller on PC that are pretty cool, review say that they are Metroid like but I don’t see it.

Spud’s Quest

Spud’s Quest mixes up the puzzle and platform sequences quite well: some require speaking to people, others are Sokoban-like (pushing boxes and other items), and several require finding and dropping the necessary item somewhere specific to advance. Some areas require gaining new abilities to progress, as well, a trope Metroid fans should be all too familiar with. Enemies aren’t annoyingly tough, and you have unlimited, short-ranged ammo to dispose of them.

Valdis Story: Abyssal City

As an action platformer with a heavy dose of exploration, Valdis Story does this aspect of its job well. There are plenty of enemies to dismantle and treasure chests to unlock throughout the levels, so progression tends to move at a decent and engaging pace. The normal enemies don’t pose too much of a threat. You’ll have to pay attention while fighting groups, but single foes are dispatched easily enough. These fights are best used to learn the ins and outs of combat, how to use the dash mechanic, and discover the uses of your magic spells.
