Maybe not new but I recently played them:
Shantae 1/2 genie hero (100 % Hardcore mode, one of the few games I've 100 %)
Sine Mora EX (not finished yet because of SMO, but damn "Challanging" is difficult)
Biggest disappointment:
Earth Atlantis (the game is not "bad", it's just really really mediocre)
Eagerly awaiting:
Hollow (possible big let down since I've hyped it up for myself)
