Slot Crawler is a 1-bit roguelite where a slot machine fights your battles for you.

How to play. Your hero runs right and fights on his own — you never control him directly. Everything he does comes out of the machine below: pay a coin, press SPACE to spin, and stepped paths of matching symbols fire off weapons and heals in the battle above. The one real decision is holding — click a column (or press its number key) to freeze it before the next spin, so a half-built path survives and you get to finish it instead of hoping the next spin hands you a whole one. Coins run out, so a bad hold costs a spin you don't get back. Dying converts the run into meta currency for a two-branch upgrade tree, and the next run starts stronger and reaches deeper.

Prototype, and sorry in advance. Seven days, one person. The whole loop is in — run, death, upgrade, deeper run — but content is thin and balance is barely tuned. There will be bugs; if something breaks or reads wrong, leave a comment and I'll look.
