(3.01v) Very addicting game. Love the gameplay loop! I would love to see more!
Game feel is good. I like the balatro style card movement, CRT screen effect and level intro and outro. I would like more pizzazz/partical/card visual effects that tie into the mining/pixel theme if your sticking with it. The overworld is cute, but I would like some backgrounds while playing to reflect the location I'm in. I wish the location had some effect on the gameplay.
Game play wise, I wish you could have branching paths for different locations or events (I thought it was initially, based on the navigation in the overworld) but as I said in the beginning: very fun finding synergies, combos, and managing priorities. I would also like seeing more card modifications other than upgrading resources. Maybe adding equipment/events that modifies actions/tools? (Can you tell I like Slay the Spire?) But just things that would make it more fun/replayable.
Game balance wise, it feels like that the optimal strategy is the only strategy to win (ie no build variety to win the game). I was stuck on the level that required 90 scorium for a while until I realized what cards I needed to win. And that combo of cards depended on the RNG of the early shops. (The combo was early goldmine/0 cost resource generation into walkie talkie to duplicate resource cards to 7 value, into salamder, campsite, draw/energy cards, wrench) And it took a while. So, personally I want more build variety and maybe some other gameplay modes for replayability.
Overall, great game and I would love to see more. Good luck!
