Was the fact that this game was made by a Dutch developer, Two Tribes, the reason I downloaded Toki Tori? Perhaps. But the great impressions by various professionals over the world was a good indication of the quality of this game. I've played through it and wrote a review for the website I work for, but I'll give you my short impressions here as well.
Toki Tori is an awesome puzzle game, plain and simple. It reminds me of those old PC platform games or the countless free Flash games you can play on the web. It's just level upon level of platforms with hard-to-reach eggs you need to collect. You move this chicken by pointing the Wiimote at the screen, which works fine, and the little animal has various moves (although they're limited to a certain amount), like building a bridge or freezing enemies, to make it easier to get to all the eggs. There's no time limit, but it can be hard enough to find a way to reach all the eggs in the later levels.
What's so good about Toki Tori is that it sets out to do something very simple at first glance (entertain the player with a simple concept) but that so many developers seem incapable of doing these days. It's a perfect fit for WiiWare but truth to be hold, these are games I'm likely to buy in the stores as well, in contrast to a lot of ambitious big butget games these days.
There are some flaws, of course. The game would have been so much better with a time trial mode, so players could try to get a best time at the levels, and the game doesn't exactly ooze character. It all looks kinda cheap, or secondhand. It's hard to describe, but there's just something uncharismatic about the main character. Thankfully the world around him is varied and nicely rendered, so I'll stop complaining right now. I had great amounts of fun with this game and if you're still pondering on what game to buy for WiiWare, this and LostWinds are great additions.
