Made by japanese indie developer Fox Eye, this interesting side scroller with puzzle elements is kind on the hard side.

In Holdover, you play as Marie, a girl who just woke up on some sort of cryogenic chamber in an abandoned complex and is trying to figure out what happened to her and the world.
I have to add that some of the art on the game is a bit on the erotic side (some nudity and almost see-through clothing), though nothing explicit (might make some unconfortable though).
Probably has something to do with the artist doujin background… 😛
As the developer himself states, the english is sufferable at most.. but it’s understandable, and I only have to thank him for trying to make an english version.
Finally, a word to the short tempered: This is a very hard game. Specially the underwater parts because the timing to avoid drowning is pretty tight.
Click the image or this link to the official Holdover website. After everything loads up, there’s a big blue button to download the game.
It’s compressed in .lhz extention, so you need 7-zip or some other decompressing utility.
