Hey!

From the Steam Sale, some casual games about playing with the odds:

• Peglin is quite fun and short. The more pegs you hit, the more it damages an enemy. Highly replayable with all the modifiers making each game unique.
• Roll is similar, modifying dice to get the highest score in 2500 rolls. There is way more complex calculations, but I like how messy it gets.

From the ones already on the library, just Hollow Knight which has been a delightful yet frustrating experience. The soundtrack is stunning, and I love me some platforming challenge.
