Pixeljunk Eden made its way into my library on a whim and it turned out to be a solid decision.
This is a good game to play for relaxing and quiet time. Gameplay consists of leading a small creature from plant to plant or to rocks via jumping or spinning. In later gardens there are additional movement and puzzle mechanics which complicate the game in a positive way. The game introduces new mechanics slowly, which keeps frustration to a minimum. There's some need for planning and quick movements at times, but it's not a game that relies 100% on twitch reactions. The main goal is to find all 5 spectra in each garden and there are additional challenges such as collecting all 5 spectra in 10 minutes or unlocking all seeds in a garden. You can go as quickly or as slowly as you want through gardens, which is a very attractive freedom to me. It has an odd graphic style which is pretty fresh. Each garden has its own graphic style and color scheme, which change as you collect spectra. The music is made by an independent Kyoto artist and is a good selection of electronic trance with light beat (get the soundtrack bundle, it's worth it).
Overall, this is a solid puzzle game that has a lot of fresh and interesting attributes - a great thing to play and just relax with.
