Obviously you need to check my metroidvanias collection.
Though since the collection is for any metroidvania I've played and confirmed, their playtime varies from short, mid to long. And also some of my games are also there so I've warned you before browsing the collection.
Do you want my recommendation from the collection?
Alright, please go to the collection link for game's link. Here's my recommendation:
1. XGA
2. Lightkeeper
3. Hyper Pixel Ten Thousand
4. Heart of Ruin : Final Columbus
5. Buntroid
6. Treasure Hunter Man
7. Treasure Hunter Man 2 (if you're willing to pay the price)
Did someone say Metroidvanias? :D

The gameplay time of these games vary, but I can do these games within 30-90 minutes.
