Super cool! I love a big number game so as soon as I saw the screenshots I was excited to try it. Everything was super satisfying feeling. I also liked the twist on the goals that normally are set in these kinds of games. Typically I notice the goal is in 1 "currency" and then upgrades come from another currency pool (like balatro, your score vs dollars for upgrades). Making the goal and upgrades use the same currency sets up tradeoffs, where you have to decide how much to bank for the next round's goal vs how much to invest in upgrades. I do think it's more unforgiving, but I had fun strategizing about it! One gripe, I had a run where I bought 20 blocks and kept investing in 2x upgrades but never actually got one. I know that's just RNG but a shuffle bag approach might have been nice because I felt a bit frustrated. Nice work, excited to see if you develop this further!
