I switched my MP5 to semi-fire mode and the cursor disappeared. I'm not saying my ability to score headshots was dependent on the cursor, but let's just say I lost right after that :P Please fix.
After passing the first level I had accidentally chosen to replay the level, so I did. After I finished the level for a second time I went to the level select and it said that I had finished the second level. I'm not complaining about that but you might want to fix that so as to not confuse other new players.
