Yup, it is it ;), I like how it teleports you back if you get the coin, actually, when you're jumping you are kind of too high :1 but it's okay, please unbug stucking in walls ;).
If it is your first Jam, don't worry! This isn't going to be bad, the game will be interesting for you guys! You'll be participating for some time. Remember it isn't scary or something ;). I have thumbs on you!
