Roller Deck (The Card Based Maths Game)

logo - 1.png

RollerDeck is my second public game development project after Ball20x2 (a quick little game for the GM20 game jam in 20 hours).

Roller Deck is a game involving matching cards together.
Match the cards - Reach the goal!
The rules to this puzzle game are simple:
Put your card over another to add, subtract, multiply or divide it with the underlying card!
Your goal is to unlock each locked card using a matching Key Card.

Each level is procedural generated (even in this early state each level is 100% possible).

in this early build quite a few things are disabled for example help, leader-boards,
options, even the level progression code had to be very much simplified due to time the
strict time constraints and it being a one girl team they wasn't finished to a usable state do they where disabled.
these features will be added and improved in future builds.

Made by me (just one persion) in just under 5-6 days for Game Off 2019.

A latter build will be published for JamCraft 4 (what it was originally designed for).

if you have any opinions, criticisms or ideas about/for this game good or bad ill love to hear them,
and thank you for playing :3

(in a publicly playable state at least).

there is something surreal about someone playing something you created, any ideas how to make it a bit easier for those not as good at math, oh and quite a lot of bugs you experienced are fixed in the 21.45 build. though the games still in development it still has quite a few problems when it comes to these kinda things but thats why I'm play-testing.
