Thank you very much! I'll be honest, most of my play-testing was done with a lot of money and high upgrades so I could test other stuff, so i never realized how excruciatingly slow it is at first. When i asked some of my friends however they said it was fine, though looking back to it they probably just didn't wanna hurt my feelings or something (which is stupid, I WANT criticism). If i ever do make any more updates, I'll definitely make the start a lot easier (and of course add a saving system)
As for the UI, I'm very glad you liked it, this was my first ever project in Godot so i was a bit scared of how ambitious my UI idea felt, but it was a lot easier to make than I expected, and i think I've fallen in love with Godot's UI creation workflow.
