No new posts since December?!
I'll do a third post in a row, because I've been playing two indie games that I want to spread the word about.
Ms. Splosion Man - a really fun 2D platformer. You can play in single player or multiplayer co-op, and unlike the New Super Mario Bros. series, the co-op here is not just an afterthought. You will need to work together with your partner(s) or you won't get very far. There are 100 levels, 50 for single player and 50 different levels for multiplayer, so even if you only plan to play the game alone, or only with friends, you get a full game's worth of content either way. I absolutely recommend this over New Super Mario Bros. Deluxe and it's a heck of a lot cheaper as well.
BQM - BlockQuest Maker. Until Nintendo decides otherwise, this is the closest we've got to a Zelda Maker. The userbase is small (understandable since it's hard to make your game stand out in the eShop among all the trash that gets released every week) but there are some really creative levels on here. Since you can make your own story be told through NPCs and leave signboards with hints for the players, I find this to be a little more creative than Super Mario Maker.
