First playthrough in browser- I didn't know what my goal was or what I was supposed to do. Some of the buttons didn't seem to work, and there was a lot of text that covered up the world during playthrough.
On phone- Accidentally skipped through the tutorial and then couldn't go back. Clicking on objects/things on the map the text pops up and goes away way too fast to read. Definitely feels better on the phone, and was way more intuitive. I only got 1 start on my first planet I didn't understand the grading system. It's not entirely obvious to me what the purpose of floods and Armageddon would be but for a short jam it's a really clean build and looks nice!
