Hi congrats on making ur first game. It would be great if u added in a tutorial or a text at the bottom to tell the player about the controls. Im still not sure what the controls are. All i did was to smash all the keys to pick up a box and to put the box down i have to press the mouse button apparently. U might want to standardize picking up and dropping to be the same key. Also u can make the movement speed slower at the start of the game for the players to get used to the controls and gameplay. Then u can increase the movement speed slowly the longer they play the game. Overall this is a good attempt. Keep up the good work!
