It looks like a replica of a tutorial with 1:1 assets from that tutorial. It's also submitted to multiple jams. No originality brownie points for you :)
Yes, it's my first game. I learnt and added health system and moving platforms. May I ask if it's illegal to submit multiple jams? I'm new to gamedev and jams, sorry if I make a mistake.
No, not illegal. But it may be against the jam rules, depending on the jam. And I'd consider it contrary to the overall spirit of jamming. The only actually illegal thing you can do in a jam is to use copyrighted assets or code without attribution and permission of their owners.
