Thanks for playing! I really appreciate it! Before I published I had actually made a sprite with running and jumping animations, but it caused too many bugs to put in after the game was already finished, so I scraped that. But I really cannot express to you how much I am thankful to your for your comment!
Update: Just played your game Digger, I really like the concept of cave exploration. But I was really confused when I started because there were no sounds to indicate that I was mining, I can tell you put a lot of work into the game tho, that alone is enough to deserve my respect, I wish I had your dedication. My only criticisms are the lack of sound.
