Thank you for the Feedback!
Here some answers:
1. I'm a self taught developer and haven't really looked into Screen size settings yet. Same goes for nr. 3. regarding android displaying :/ Maybe one day I will find time to optimize this. 2. It annoys me too but I always forget to fix it. Hopefully sooner than later ;) 4. Some say slime, some say STR, but I say a lot will change regarding balance anyways, so I won't change too much at the current state :)
Don't worry about supporting with money, I'm happy for everyone who enjoys my game!
