Pretty cool especially if it's your first jam !
I like how the game quickly adds that "Lost Vikings" element where you have to swith between characters and go one at a time, it's an interesting take on the theme as well, the pixel art is really well made as well, also the self made (i suppose) sound effects are awesome, made me laugh cause there's a lot of jumping in the levels so the Dwarf's like "Hyup Hyup Hyup Hyup"
Congrats dude its a neat game :)
