Thanks for the response :) When selecting an upgrade, I can use WASD to move and can disappear off the screen. I am able to come back into view if I move in the other direction.
ah yes! that is intended, so that you can navigate the upgrade tree as it gets pretty big :) you can also do that by zooming with the mouse wheel or my clicking and dragging. What do you think about the game?
Sorry for my late reply! Thank you for clarifying. I like the game and the sound design/graphics. I appreciate the opportunity for different types of upgrades too!
