Hidden Through Time is an absolute gem of a game. The basic idea is simple but couple that with the scale of the levels and some of the obscure hints it'll provide plenty of hours of hide and seek fun. A must have for anyone looking for something a little different to get lost in.
La Poule Noire have done a fantastic job with Edgar: Bokbok in Boulzac. It's a funny, feel good time of a game that doesn't take itself too seriously but delivers an enjoyable story filled with likeable characters and beautiful artwork. Edgar: Bokbok in Boulzac does a good job in introducing a humble new hero that everyone will enjoy.
While Mosaic is a good game, it's hard to describe it as enjoyable due to its subject matter. It has the possibility to hit a bit too close home for some, but the overall message once you hit the end might be worth it. It is by no means a bad game, just very heavy handed when it comes to its subject matter.
Hardcore Mecha doesn't bring anything new to the table, but it is extremely enjoyable. While having Japanese-only VO could cause you to miss dialogue in heavy action sequences, you might be having too much fun flying around shooting things to even notice.
While Home Sweet Home doesn't bring anything new to the table for first person horror puzzlers, it does stand out with the inclusion of Thai horror folklore which is truly terrifying. It's let down with a couple of bugs but it's not a bad way to spend a few hours.
