This game gives me fond memories of playing old D&D CRPGs. I think you did a great job with the 3D levels.

I think I need some guidance on how to make progress. When I purchase a weapon, armor and shield from the store, I seem to only have enough AP to equip the weapon, and I die against the first enemy. I then tried training on a stat that grants AP and I was able to equip everything, but the enemies are still hitting me for 40 HP so I die against the third enemy.

I've only played a handful of times so far, but I can already see the tremendous amount of work and polish you put into this game, and I can see there is a lot of depth in the mechanics and lore as well

P#79164 2020-07-11 14:39

waynaul Thanks for your post.

Although not as complex as the old D&Ds, it has more mechanics than it can explain in the game screens.
I think it's a mistake in a game, so I'll try to correct it.
Below there is an explanation of the mechanics.

Combat Effects

  • Stun : depletes target's AP (target AC + Weapon Level)
  • Blind : blinds the target by halving the chance to hit and double the chance to escape
  • Poison: reduces the target's HP each turn of the target (1 + Weapon Level)

Combat Weapons

There are 3 types of weapons

  • Laser (Energy Weapon - ENW Skill) - small probability to have blind effect
  • Guns (Kinetic Weapon - KNW Skill) - small probability to have stun effect
  • Blades (Melee Weapon - MLW Skill) - small probability to have poison effect

3 types of grenades

  • Stun grenades (Throwable Weapon - TRW Skill) - stun effect
  • Flash grenades (Throwable Weapon - TRW Skill) - blind effect
  • Poison grenades (Throwable Weapon - TRW Skill) - poison effect

Combat Armours

Armours that can protect from the 3 weapon types

  • Kinetic protection against Guns
  • Energy protection against Lasers
  • Melee protection against Blades

E.S.: If you have an armour that does not protect against Kinetic weapons, an enemy with a Gun does to you the maximum damage that his gun can do... and vice versa.

Armours have a small protection against grenades (it depends on the difference between grenade and armour level)


  • Medikit : restore HP
  • Stimulant: adds AP during combat
  • Unblind : removes blind effects
  • Antitode : cures poison

Combat Actions

  • AP: represents the Action Points Pool. More AP more actions. Can be negative.
  • AC:
    • character: represents the number of AP (+1) that a character restores each turn
    • weapons : represents the number of AP consumed when used or when wielded
      when wielded reduces player AC by the same amount
    • armour : represents the number of AP consumed when weared
      when weared reduces player AC by the same amount
    • items : represents the number of AP consumed (or added for stimulants) when used

Character progression

Currently the maximum level that can be reached is 9, so when you get to level 10 the game ends.
Fore each level you gain 2 skill points (SKP) for a maximum of 20.
Each skill can have max 4 points.


Factions have 2 properties:

  • Power (PWR): indicates how close the faction is to controlling the Galactic Council (90%)
  • Relationship (REL): indicates the relationship with the player.

If a faction becomes hostile to you (REL<25%), it will no longer give you missions.
If all factions become hostile to you, the game ends.
If a faction gains control of the Galactic Council, the game ends with a different end per faction.

same comment - first encounter (unpredictable but ok), I miss all my shots.
Tried multiple times, first enemy = insta death
Suggest to improve game balance!

P#79201 2020-07-12 10:44 ( Edited 2020-07-12 10:48)

Combat issues (except unpredictable) where solved with version 1.0.4 and bilance improved.
For sure the game balance needs more tests.
Tank you very much for your post.

Hello @ViperSnake75, it seems that the game is broken, at least on this page.

There is a Syntax Error L181 TAB2

P#88271 2021-02-27 22:16

@Voljegaaa. I have released a fix :)
Thanks for your interest in the game :)

P#88314 2021-02-28 20:40 ( Edited 2021-04-28 06:12)

Sorry I dont have a gif for you.

Encountered this bug on a mission -- I was in my second room and ran into an enemy. I went into my inventory during the fight and then pressed left or right I believe... Might have even pressed both at the same time. Then this error came up.

Fun game though! :D

@professir Thank you for playing the game and for bug report :).
I have fixed it today with the 1.2.6 version :).
And, as allways, any comments or criticisms are welcome :).
