Far too many things from making this game perfect
But theres nothing keeping it from being damn good. Just fix the glitches and bugs that you know are there, and change the font of the text, it's too un-mario-esque. you should change the logs to those donuts from mario 3. other than that, it would be awesome to use the fludd offensively. Also, the game should save the number of coins, and if the player falls to their death, it shoud happen faster. It's takes like 10 seconds when it should only take 3, tops. Kepp up the good work.
