Ah, yeah this is a great baseline for sure, like Maoaii said.
The main issue I see with this game is balancing. Run it through a couple more times with friends, and see where they fall short. For me, my contestant died because I kept being given the choice of Spikes or... Spikes. I didn't feel a lot of agency. There are also some notes on the value of certain actions. Like dragging the card onto the slot – there's nowhere else to drag the card to, so maybe it could just be a click? Or maybe you want to increase player agency and create more slots that can be dragged to? Like maybe the contestant hits a crossroads, and you're not sure which direction they'll go. So you try to setup a trap by predicting which path they'll take. Could also be interesting to lay traps in advance, down the pipe. So you're not just putting them in the very next slot, but maybe 4 slots down.
Oh man, this game would be fun with multiplayer. One friend is the contestant, the other(s) are laying traps. Or Twitch chat could lay the traps, too. That's a cool concept.
Anyway, great contender, awesome start, and if you build on this again in the future, tag me and I'll give it another play!
