Suggestion #1 : The colour of the arrow because when it is black it is hard to see.

Suggestion #2 Change the input box so it doesn't come up with a new window (Are you using gamemaker)?

Bug #1

There are 2 create usernames in the screenshot above.

Bug #2/Suggestion #3

How do I make money?

Hey! Thank you for being part of this games development, as you now know the user input box has gone and I am going to redesign that screen with the 2 "Create Username" buttons.

Yet again, thank you and I hope you stick around for the next release which is coming very soon :)
