Project black sun, dustforce, and dungeon defenders (cant say I see the attraction with that one)
I really enjoyed PBS but it felt unfinished at times. It relied too heavily on "visual storytelling" which wasnt very good, but everything else was great.
Dustforce is really cool but I feel it wouldve made a better action/adventure game. Striving for perfection just to progress isnt very fun.
Dungeon defenders is meh. Another game that wouldve made a better action/adventure. Tower defense is boring.
Definitely recommend the first two though!
