I really enjoyed this, the SFX were ~nice~. I kept falling into the gameplay loop and it was so satisfying to discover the little houses and trees. Super simple but flawless execution! Once I started making passive research points I felt unstoppable. You also struck a great balance with how much each upgrade gave you, it felt like a trickle, and a great one at that. Great job! You definitely accomplished what you set out to do on your UI 'Expedition' ;)
