Thank you so much Bicho Regarding the pausing whilst upgrading thing: The game is gonna be multiplayer. Got any ideas to make upgrading less complicated for new players without pausing the game?
Cool, if multiplayer is in mind then, of the top of my head, you can do something like what Evolve game did, when selecting an upgrade you go invulnerable (or shielded) for a few seconds until you select the upgrade or the timer runs out (autoselecting an option),
