Very good metroid and background story.
Got endeared to this game, 9/10 for me.

----
- Assign Mouse buttons for this game or any other than doesn't use them.

Used free glovepie.exe to play with Mouse buttons, assigning any key chosen for me in the game choose keys layout options.
Just paste this in glovepie empty text window.
Save.
Run it while playing.

Key.Q = Mouse.LeftButton // STEP AND STRIKE
Key.Z = Mouse.RightButton // USE INCENSES
// use any other keys be they the default game option, or chosen by you in key layout
// option, o any other keys you want not already used by the game for other things.
// also Key.any = Mouse.MiddleButton or further mouse buttons for anything else you want

(DONT FORGET STOPPING GLOVEPIE.exe WHEN NOT PLAYING)

So I buy lots of them knowing I'll finish and enjoy fully these gems.
Hey, you'll get here too.
Maybe =)

- Jump high and while chain shooting any shot essence, you float down slowly, allow gliding ahead a long distance.
(White Essence minor shot, Black Essence powerful, Ashen Essence razing longer than screen shot)
Below, infinite shots cheat.

- Jump height:
14.5000, Float, Simple Values, on Steam the addresses (vary from session to session) always ends in 8 (hex).
Used mostly 22.0, but can change to any needed.

- All essences, passives and active are 4 Bytes, Exact Value, all can be changed to 99000 or whatever.
For Maxed values for each always add 4 bytes to the base (current but full) value.
Best weapon: Ashen Essence for me.

- Experience (max level 99, some 500000), Health base value and its maxed value are grouped together (4 bytes distances each from the others).

Detail :
- Exp ends in 0 (hex) and is 4 Bytes, easy to find as each foe killed shows the points gained.
- Add 4 bytes and you have Health base value, Float, Simple Value, ends in 4 (hex), can change to 99000
- Add 4 bytes more and you have Health maxed value, Float, Simple Value, ends in 8 (hex), can change to 99000.

Enjoy a marvelously made game !
