New feature: Card Mastery

Card mastery was added today. Summed up it works like this:

  • Card Mastery (CM) is connected to your profile.
  • CM is 100% cosmetic and has always ZERO effect on gameplay.
  • Seeing these cosmetics can be totally disabled by you as a player if you for some reason enjoy vanilla.
  • Each card earns XP when its played.
    • More XP on a win.
    • Even more XP when winning all 3 lanes.
  • XP can never be lost from a card.
  • Max card mastery level: 100, (but stats keep tracking beyond that for fun).
    • Currently and on average this means it takes ≈675 matches (if 50% win ratio) to max a card to lvl 100. This can easily be tweaked from textfile (locally)
  • Win screen expands downwar showing which cards  earned, how much, and their new XP/level
  • Dev tool: set a card to level X, or grant Y XP
  • The card mastery track grants you rewards each 5 levels or so. Rewards can i.e. be any of the following
    • Card frames
    • Cute or meme stickers to plaster on your cards front
    • Alterantive card art
    • Parts of card art overlapping the card frame
    • Pimping card effects, sometimes unique to that card only
    • Sound effects for that particular card
    • Player titles, for your profile
    • Alternative appearance for the NRG/ATK container
    • < More to come? >
  • Game allows us to define each mastery track in detail for every card.
  • RNG: Game makes it possible to let us make the mastery track randomise or semi-randomise in what order its mastery rewards are unlocked for that cards.
  • The “big” mastery rewards will let you select 1 of 2 or 1 of 3 rewards.
    • What is not select will not be available layter on in the mastery track: This makes the selections actually mean something, however little.
    • What was not selected and what is “gone” can still easily be obtained by trade with other players. . [This is a feat. yet to come when trading is in place]

While the system/code is there already for all of the above, the actual visuals/rewards are not there yet. They will come after the cards are done with their real artwork et.c.

Made by players, for players

No corporations. No greed.

SnapATK exists because there is an interest in creating a game that is more feature-complete and that does not target the mass market/kids or the mobile experience in particular. We believe in the power of open source gaming and community ownership. Our goals differ from the mainstream.
