"అభినందనలు. ఈ రోజు మనకు సెలవు ఉంది."
"మరి మనం ఏమైనా చేయగలమా?"
"అవును, అమిగో. మీరు రోజంతా మీ బొమ్మలతో ఆడుకోవచ్చు. ఉదాహరణకు, సోకోబాన్. చిన్నప్పటి నుండి నాకు ఇష్టమైన ఆట. నేను 435 స్థాయిని దాటలేను. మీరు సహాయం చేయగలరా?"
"అయితే, నేను సహాయం చేస్తాను, నేను మీకు చూపిస్తాను, కెప్టెన్."
కెప్టెన్ స్క్విరెల్స్ తన జేబులో నుండి పాత గేమ్ బాయ్‌ని తీసి సోకోబాన్ మోనోక్రోమ్ వెర్షన్‌ను ప్రారంభించాడు. కానీ అప్పుడు నిరాశ ఉంది. బ్యాటరీ అయిపోతుంది మరియు గేమ్ బాయ్ షట్ డౌన్ అవుతుంది.
నిశ్శబ్దంగా, కెప్టెన్ గేమ్ బాయ్ వైపు, ఆ తర్వాత అమిగో వైపు, మళ్లీ గేమ్ బాయ్ వైపు చూస్తున్నాడు. అటూ ఇటూ తిరుగుతూ మెల్లగా తన ఆఫీసుకి నడిచాడు.
"కెప్టెన్! సోకోబాన్ యొక్క మన స్వంత సంస్కరణను వ్రాస్దాం! మేము 1000 అదనపు స్థాయిలను పెంచుతాము మరియు చక్కని గ్రాఫికల్ ఇంటర్‌ఫేస్‌ను తయారు చేస్తాము."
"అమిగో, మీరు నన్ను ఆశ్చర్యపరచడం మానేయరు. ఏజెంట్ IntelliJ IDEAని సంప్రదించండి. అతను మీ కోసం ఇతర అసైన్‌మెంట్‌లు ఏవీ లేకుంటే మరియు అతని సెలవు రోజున మీకు సహాయం చేయాలనుకుంటే, కొనసాగండి."

Today we're going to write our own implementation of the game Sokoban. This is a logical puzzle game.
You can read more about it on Wikipedia. The game will consist of 3
main components (as you may have guessed, you'll need the MVC pattern).
The graphical interface will be implemented using Swing.

The foundation is laid, so now let's start building. You can think of the gameplay
as the interaction of GameObject objects. We'll have several types of them:
Box, StorageLocation (the place where you need to put the box), Wall, and Player.

The game will have several levels, and all of them will be stored in a text file. Now we'll
write a LevelLoader test stub. Why a test stub? We don't
need the full functionality yet. It's pretty complicated, so we'll leave it for later. For now:
