I'm glad a game inspired you to make your own. Unfortunately this game is currently unplayable because jumping doesn't (consistently) work. At first I thought I couldn't jump at all. After mashing Up constantly for a while I would occasionally jump.
My unsolicited advice: Start doing game jams to get practice making simple games. Don't go online to promote a game or ask for donations until you've gotten positive feedback from people you can trust for honest criticism.
