A scrollbar game, such to the likes of Hollow Knight, has many mechanics.

You control the character using; w a s d
Spacebar to jump also. Left click to attack where your mouse is, and right to dash which also deals small bits of damage.

The first boss gives the beginner player grind the game and learn about items along with how to get rarer items.

I like this game for casual gaming, it makes time go by faster (I played for 2.5 hours and it only felt like an hour).
WHICH can be what game you're looking for.

Game was made with a lot of care. Very fun.

Fun but could use some polishing.
