1. You press ALT+F2 on your keyboard, if that doesn't work it's probably due to your input mod version, i recommend taking version 1.8 which is in the ressources

2. If you play in 640x480 it WILL be pixelated because it's 480p, there are the "Enhancements" options in the graphics tab of the mod manager BUT IT IS NOT ALLOWED ON THE LEADERBOARDS!!!

3. Yes, Pastanova has amy tutorials on his youtube channel that will cover (almost) everything you need to know about amy story, the only new skip which doesn't have a tutorial yet is the Puzzle Skip Skip in hot shetler https://www.youtube.com/channel/UCXQjK5MlmULC53sNMA6_XLQ/videos

Have fun with the game! there's always the Sonic Speedrunning Discord if you need more help
