Update to 1.1

Updated the game with the newest version of GB Studio.

• Antlion enemies now work properly. Before, it was at least theoretically possible to get hit by them, even if the player didn't directly touch their sprites. That was due to technological limitations that don't exist anymore, so that shouldn't happen now.
• Fixed a bug that could cause the player to become indefinitely invincible, if they get hit and reach a level transition or level exit, before the invincibility runs out.
