Super Little Acorns 3D Turbo

This platformer on the 3DS eShop is currently on sale for $4. It's completely worth it. The difficulty curve is very good, slowly ramping the difficulty up over time, and introducing new features.
It's a little squirrel, who simply has to gather up acorns across a platfirming level, swing on ropes, jump on enemies and make it to the door at the end. There's optional fruit to collect, which unlocks costumes to wear, there's Turbo mode to unlock, and there are 45 achievements to, well, achieve. Then there are a dozen or so challenge levels, with 3 difficulties. You have to do everything to 100% the game, and seeing as you check your progress after every level, it can become addicting.
It's a pretty solid experience, if you visit it in the eShop, in the description for the game it has its review scores. Nintendo Life gave it an 8, but it has many 9's.
Don't be put off by what seems like a Baby title, as this is like Ninja town on the DS, cute but can be tricky.

Wow.  This sounds like a lot of fun.  Too bad I don't have any eShop money.  Ugh.  So many games, so little time.

Your BL told me how good it was, checked it out on the eShop, and I want it. I'm just waiting until a fav dev/pub of mine releases there games first so I have enough money for them first.

You're a bad man @Clay. You know better than to make games look really interesting when there are so many other good games coming up.

I just wanted to get the name out there while its on sale, because its surprisingly fun.
I expected it to be horrible until I saw all the positive reviews.
And it has loads of content, as in, a lot for $4, or even a very good amount for the full price. o__o
@Ideal It's 4 bucks, I don't think that would drain your wallet (although I never know).
@Knuckles Don't you have hundreds of dollars in the eShop still?
