First thing first , the 10.2 Mb file that you download from GameGotd , is not the game , it's the installer .
When you use the installer , the actual game starts to download (size 14.8 Mb) .

My PC Specifications
Windows XP Pro 32bit , Intel Core2Duo E8500 3,16Ghz ,
4 Gb memory (DDR 2) , NVIDIA GeForce GTX460 768Mb .

Downloaded and installed without a problem .

System Requirements : Windows 7 or newer (32&64bit)

It works just fine under Windows XP !!!???

About the game ...
The game starts in windowed mode .
I see an image with the name of the game and some info about the developer of the game .
I've clicked everywhere with no effect .
I must press "Enter" in order to proceed .
I see a menu , BUT , no visible way to turn full screen on .
One way to change the size of the screen is to right click the games tab located at the systray and choose "size" .
Then you can "drag" the borders of the games window wherever you want .
I navigate the menu with the arrow keys to move and "enter" to choose .
In the "help" tab I see the controls of the game .
I see that the "SPACE" key is used for opening the door and not for attack as I saw in
the description of the game in the GameGotd's page .
I choose "New Adventure" to start a new game .
I see a small text as an intro story .
Pressing the down arrow key I change page .
The screen moves VERY slow .
I see a map , but all the names are in Russian .
So , it's useless to me .
I assume that the red arrow indicates the first level location .
I press the right arrow key and veeeeeeeeeeeeery slowly , the game starts .
I am in a yard .
I say yard because in the middle of the space , there is a big cactus .
So , it can't be a room .
In front of me , across the yard , I see an unarmed guard in front of a moving door .
I try to bypass him and enter the door but he blocks my way ... in silence ...
I return to my starting point .
To my right I see another unarmed guard and beside him , a sword .
I move straight to the sword and I step on it .
The sword appears in the bottom of my screen .
So , I guess , I have it in my hand .
I try to attack the unarmed guard using the "Space" key , because I don't know what ΛMK is , nothing happens ...
I press all the keys of my keyboard ... nothing happens ...
I pause the game and start "googling" like crazy for about an hour .
Result ... nothing useful ...
No video of the game on Youtube , no review , no walk-through with some info about ΛMK ...
I return to the game and start moving further in to the yard .
An armed with a sword and shield guard comes straight at me and attacks me .
Again , I press the "space" key like crazy BUT nothing happens and I die .
I start again and go straight to the armed guard .
This time , out of habit , I use the LMB .
In 4-5 hits the guard dies and I am down to 87% health .
So , 3 conclusions ...
1) I can't attack unarmed guards ,
2) the "space" key is NOT for attacking and
3) ΛMK is LMB .
Solving this riddle took a lot out of me , so I decided to quit the game , finish this post and get some rest .
It's almost 05:00 in the morning here in Greece .
A few words more about the game and I am off to bed .
The controls are very simplistic .
No jump , crouch or run .
The music in NOT annoying , that's a good thing .
The graphics are "old school" BUT not ugly .
In general , this game is Doom shareware (1993) , all over again ...
If you are like me , who played the original Doom , in a DOS machine ,
you will enjoy this game , BUT I have the feeling that it's NOT as good as DOOM was .
Let's face it ... nothing will EVER be as good as DOOM was ... :-)
I will try to play the game , no matter how much I hate WASD controls ... :-)

Blood Island

In Brief

Find all the crystal shards to discover what will happen when the shards are assembled together.

The Game

When the game first boots up press enter for the main menu. To navigate the main menu use the up and down arrow keys and to access a particular command use the right arrow key or the enter key. to move back to the previous menu use the Esc or left arrow keys. You can select from New Adventure, Load a previously saved game or Save the current game. There's also sound options a help section and Exit buttons. The help menu shows the in game keys:

i.e.
WASD = Move
ʌKM = Attack
Space = Open the Door
TAB = Map
Esc = Main Menu

To pick up objects (weapons) just walk over them.

I find the black area along the bottom of the game menu's a little strange, sort of like the dev' forgot to include something, but this disappears once you enter the game. The game starts in a window that fills about 20% of my main monitor which is a 25'' set at my recommended setting of 1920 x 1080. Setting it higher (3840 x 2160) makes the window even smaller. setting the screen resolution to 800 x 600 almost fills the screen. you can change the game to full screen by clicking on the middle button in the top right corner of the game window. However, you still have access to these button and the task bar.

I haven't a clue what ʌ does, but I know it's the caret symbol which is a math symbol meaning true and which you can type using the Shift and 6 keys. I tried using the Shift and 6 keys while attacking, but always died.

This game is graphically akin to the early 3D shooter games like Doom and Wolfenstein; though in this game you have a sword instead of a gun (similar to the first Shadow Warrior, but not as detailed. I found it gave me motion sickness, so stopped playing it after about 15 minutes. There are health packs and other items such as flintlock pistols, crossbows and spare crossbow bolts as well aas gold to pick up to find in the dungeons and corridors, some of which are maze like.

The menu music tries to emulate the early sounds of computer games thankfully you can turn it off via the sound options. The in game music isn't much better, but it does at least fit in with the theme of the game, with a middle Eastern feel to the sound from the Arabian Knights era.
