These are some deep-cut cult indie titles.
Love started off as a single developer project that was initially available as a browser game. It then received a full release on PC titled "Love+" in 2014. The game only has 16 levels and is technically beatable in around half an hour.
Kuso is the sequel to love, but contains all levels from its predecessor. It features 25 original levels which can be played on their own or with the levels from Love for an extended game that will take about an hour to complete.
The gameplay is very much in the family of Super Meat Boy or Celeste, but with the ability to make your own checkpoint wherever you feel necessary.
Here's the link to LOVE although it's unnecessary if you purchase Kuso.
Also it has some banging music.
Might be a decent use for some of those gold coins
Kuso is an interesting title considering what it means in Japanese 😅
