A good little builder game type! I'm a fan of these, so I enjoyed doing diabolical things to watch the funny number go up. LOL
I agree with the notes on scaling, that's a critical part of the fun factor! Rewarding the player with new mechanics, new ways to challenge their ever-growing funny numbers, and new funny numbers tend to be the largest engagers, so I feel like you have a solid base for doing that. The central flat green field upon which we build could take some biome-level TLC and become this gorgeous place that your mass of pemaloes detonate and turn into rock (rock) factories.
A crazy idea I got while playing this is, what if you could control the pemaloes you amass pikmin-style, and leverage them as a resource towards larger unlocks? 😱-- but enough of that, I had a great time with this. Thank you for submitting! 🙇♂️
