Thank you for your feedback, and for creating this topic.
I'm sorry you faced this issue.
Have you tried playing the game in fullscreen mode?
Click on the following bottom right Expand Icon:
In this mode, keyboard controls won't scroll the screen.
Then, press Esc key to exit full screen mode.
If you have a gamepad connected to your computer you may use it to play the game instead of the keyboard.
Refresh the game page, on the Start Screen press any button on your gamepad and the game'll start.
I'll probably add some quick settings on the Pause menu to allow changing the input type.
Likeso you may easily switch from Keyboard to Gamepad or vice-versa, instead of refreshing the game and loosing your progress.
Let me know if this helped you so that I can mark this issue as Resolved.
Thanks again for taking time to write this post.
I hope you enjoy this early prototype.
