Youdunnit (4Mb)
Youdunnit is a platform adventure set on board a spaceship in outer space. It’s a memory mystery game, as you go back in time.
Whodunnit? Why Youdunnit! And you have to remove all traces fast! From here it gets complicated, very so! A murder has been accomplished but you committed the crime! Well Youdunnit, but you have the means to travel backwards through time and undo any incriminating evidence, and so escape justice and the natural order of things! Instead of putting things to right in the past, you attempt to wipe any record of your grim misdeed from history! But not to undo the murder itself, as there may be very good reason for you to want the victim to stay that way!

A detective has arrived on your ‘doorstep’ investigating the murder but you have the secret of time travel to manufacture your excuses, and blight those of other; the only thing being the slight matter you have to ensure that you are not caught out by a time inconsistency, and also have to prevent others from having a plausible alibi. If you fail in damaging others alibis, leaving you as the only suspect, you’re cooked. Again, if your past isn’t sorted ‘correctly’, any gaping holes in the time continuum will catch you out and put you under very close arrest!
It’s rather; as in very, very clever as you travel and re-visit 1 hour time slots from the past, eg 1 hour ago, 2 hours ago etc, but have to be extremely careful not to cause a ‘causality hole’ in time. So for instance if you throw a cat 1 hour ago, you have to be sure you pick up the cat two hours or more ago, and believe me, you do not want to cause a causality catastrophe! Not now, not ever! Or you will be the one thrown out of the airlock, into very airless deep space!

But you have to be smart enough to frame someone else, and avoid for instance leaving the weapon in the room of someone who has an alibi, so you’ll need to make sure you are fully knowledgeable about everything that happens. You need to keep track of everything you are going to do and the order of doing things.
This does make it more on the difficult side as you travel backwards in time, and keeping a note of events from a visited hour’s time slot is vital if you’re not to get caught out, 1 hour or several hours beforehand! The game ends once you finish re-visiting the murder scene from seconds after the crime, provided the initial or subsequent hours after the murder haven’t caught you out or you haven’t got caught out by the questioning.

So avoiding any time paradoxes means your lies will have to be totally consistent! And the detective will home in on the slightest error!
There isn’t a tutorial so it might take a few playthroughs before you get the idea of how to play the game, and what is happening where. And it might take some serious mental effort too!
‘Spacebar’ to select/advance dialogues, and ‘arrow’ keys to move/ in menu. ‘F’ key to switch between full-screen/windowed mode.
To win, you’ll need to: keep causality, keep at least one other crew member as an ambiguous suspect and frame that crew member when the time arrives.
It’s a challenging, unique puzzle game where you're piecing together the evidence of a murder after the crime has been committed, in reverse order during flashbacks and playing as the murderer trying to frame another crew member.

Do bear in mind that it is difficult to play and at first you probably won’t have much clue what is going on! But if you are prepared to play it several times to get the gist of what is happening, and take notes where necessary, it’s a whole lot of fun, a bit like Cluedo in reverse!
The latest version (2.2Mb) is designed to be 'slightly' less confusing, with the original (4.4Mb) still available to download. (nb There is some adult language on the download page in the game review)
