First things first, ensure that your project files all work correctly before submission. Having to rename files isn't ideal. This is a decent attempt at a platformer, with some nice visuals.
This feels a bit basic, with only rudimentary mechanics and little attempt to make the game unique. Why should I play your game instead of the other submissions? Some of the environment assets could have been improved, flat colours against an otherwise colourful background doesn't look too good. In addition, the game feels too short with only two levels. Given your submission time, I feel that perhaps there was little to no playtesting and some parts of the game had to be rushed so you could submit on time. This game is in need of polish and expansion.
Overall, you have submitted something and it is clear that an attempt has been made. Consider what you could have done to make a better product and use that knowledge to improve yourself going forward into future projects.
