If things are a bit strange, just double-click the green flag to play perfectly (I hope so). Note: This game will receive updates, so make sure you comment down below ideas or bugs detected pls! :)
Credits to @scratchbuilder21 for the player code (movement and wall jump) and to @BunzoBunnyLoverX263 for the rest. This game took some hours to be made (wrong coding, bugs...), but came out pretty well!
