Eufloria is a very good game. I suggest enjoying the original game before using the trick in this guide, or only when you want to lower the game difficulty.

Go to the game directory ...\SteamLibrary\steamapps\common\Eufloria HD\res\Win32\ . There are many LUA files. The files Level_01.lua - Leve_25.lua are for story mode (Level_03.lua - Leve_25.lua also correspond to dark matter mode). The files Level_Arena_1.lua - Level_Arena_8.lua are for skirmish arenas mode.

Say if you want to get massive super seedlings at the beginning of level 25, open the file Level_25.lua with any text editor, then find the following line:
The line corresponds to your initial asteroid in the game. To get super seedlings, add following lines below it:

Note that there is a colon above, not dot.

Below is how the file Level_25.lua looks like after the editing. I found "a.Owner = 1" at line 37, and I added "a:AddSuperSeedlings(999)" at line 58.



In some LUA files there are multiple lines of "a.Owner = 1", because you have more than one asteroids in those levels. Be sure to add "a:AddSuperSeedlings(999)" after the first "a.Owner = 1", because other asteroids may be hidden at the beginning of the levels and you cannot use the super seedlings if you happen to add them to a hidden asteroid.

There are some additional modifications you can do. In the screen shot above, I also changed line 36 to have a super initial asteroid (max energy, max strength, max speed), added line 59 to extend its send distance, and added line 60 to have at most 20 trees.

Remember to save you editing, then start the level 25 and enjoy you super seedlings as in the screen shot below. Here, there are total 1079 seedlings, that are 999 super seedlings plus the original 80 normal seedlings.



You can do the editing while the game is running. Restarting a level makes your editing effect. It is handy for editing one level after another.

To revert, simply remove the lines you added. If you edited many files and hope to revert them all, an easy way is to right click on the game in your steam library, and select Properties... -> Installed Files -> Verify integrity of game files. Steam will help to restore all the files.
