Roll Before Ruin
A downloadable game for Windows
Roll Before Ruin is a real-time auto-battle strategy game: roll three D20s, bend fate, and break the alien Hive Core before the extinction countdown ends.
You are the Dicebearer. Plot routes from humanity's Last Bastion and your squads march, fight, and capture on their own. Every 12 seconds a fate die charges — spend it now, or save up to three and match aid types to trigger Resonance. Mobilize, Inspire, Fortify, Heal — and spend Fate Power to reroll a die or nudge it to an adjacent face.
At zero, the battle isn't over — but the Extinction Beasts start hatching.It is extraordinarily strong, yet fate may grant you a slim chance of survival......

《末日一掷》是一款即时自动战争策略游戏：掷出三颗 D20，扭转命运，在灭绝倒计时归零前攻入异星母巢核心。
你是"执骰者"。从人类最后基地规划进攻路线，部队会自动生产、行军、战斗与占领。每 12 秒充能一次投骰：立即使用，或攒满三颗凑出同类援助触发"共鸣"。征召、鼓舞、坚守、治疗——消耗骰势还可重掷或翻到相邻面。
归零并不等于失败——但灭绝兽将开始孵化。它极其强大，但或许在命运的指引下，你也有一线生机......

First off, I want to say sorry to everyone playing. This is my first time making a game, and I ran into so many hurdles along the way. I simply ran out of time in the end.
I only managed to get the final build uploaded for the Windows desktop version before the deadline. The Web build is still an early version with known issues, so I’ve had to take it down for now.
I know for the jam, most people expect to jump straight into the game in their browser. Having you download an EXE instead is such a hassle, and I truly apologise.
The Windows build is the complete final version. Thanks for your understanding, and I welcome all feedback!
Thankfully I uploaded the game with one minute to spare. My heart’s still racing.
