Hey, thanks for checking the game out and your feedback! I do realize that it's a bit slow going. Originally, it was much faster, but I ended up changing the pacing to match a more typical incremental game. I have debated that decision afterwards hahaha. I do agree that the text can be hard to see sometimes. We did allow for scrolling/zooming in and out on the upgrade tree, but the controls were also in small text at the bottom of that page haha.
We are happy that you enjoyed it though!
