Put about 50-55 hours in this little game Monster Sanctuary recently.
Heavy, heavy Super Metroid feels
Heavy Pokemon feels.
This game plays like a Metroidvania in how you navigate the map and how you unlock new areas with abilities (Abilities you gain from collecting monsters). The big difference from Super Metroid: the combat isn't Action based, it's turn based Pokemon style with battles involves 3 vs. 3 monsters. You collect eggs to hatch new monsters as you fight. You level up the monsters, allowing you to choose new abilities and Passive bonuses to tailor your monsters however you like. You can build teams that play off each other's strengths, like a team of 3 Goblins that share extra bonuses, or you can mix and match. You can also get eggs from boss fights depending on how well you do (You get ranked on performance 1-5 stars, a 5 star match will always yield a boss egg and you can refight bosses back at the main base).
There's 111 monsters you can collect, each has different abilities and build types: tank, healer, damage, buffer, debuffer, etc. Most monsters can fill 1-3 builds or more depending on how you build them, but obviously focusing on 1-2 roles is typically better than spreading out too thinly.
There's a simple plot, not a ton of dialogue or complex characters. There's a lot of secret walls you can find, plenty of treasure chests hidden around (Including some you can't access until you unlock new abilities, also very Metroid-like). If you enjoy a Metroid-like platformer and/or Pokemon, this is a fun little game for cheap. The 16-bit sprites are a nice touch too, as is the SNES like soundtrack.
One nice thing this game has that Super Metroid didn't have: you can put little icons with notes on the map so you can remember where to come back if you missed something you couldn't access yet. Really helps my old ass, and I wish I knew you could do that before I got halfway through the game
