Thoughts On 2D Platformer Game

I made this 2D platformer/obby game a few months ago and my friend suggested I post it here. So, TIAG (This Is A Game) is a singleplayer 2D platformer, it released with 5 main levels and now has 7. It also has 1 DLC level as of now (at least 3 at some point in the future). I am posting this to get some feedback on the game.
