Added UI for players to see what upgrades they've taken on the pause menu and at the end of game screen.
XP pickup's color changed. Late game, too many XP pickups were too noisy and made it harder to see enemies, so hopefully the new darker color muddies the scene less.
Small tentacle monster's eyes are now slightly bigger to make them easier to see.
Added options for screen resolutions
