since you already over the 3 hour time, you should've just work to add some more level. i can't believe it only has 1 level (or 2 if you count the first one). it wont take too long since you already finish the mechanic. oh yeah and add a restart button, thought i have to pick up the chest since you didn't tell me it's a sokoban lol. you may want to add some gameplay detail on the desc since there's no instruction anywhere on the game
Anyway, GL on your future project
