A downloadable game

A one-man project I've been working on for the past week or two. Check it out on gamejolt!

If you like the game or somewhat enjoyed it, feel free to leave a tip to know I'm doing a good job! I will leave the game at $0.50 as the maximum tip. I'm not really sure how this works, so I don't know if you can really tip someone.
