No Time To To Mine - I think you spend too much time for the UI, which would have been better to invest in gameplay and at least some audio, as in two days you really need to focus about what is fun to play. The upgrades only work best, if the gameplay base is fun, then they can add more fun to it. Even though I like Factorio and Satisfactory and those games, I think it was a tough choice to do such a game in 2 days.
But additionally you streamed it, which was making it harder for you to concentrate, so you gave yourself a handicap I think.
