Yeah, ofc. Obviously, if this was a longer game jam I'd recommend an in-game tutorial, but aint nobody got time for that (in a 48 hr jam). It was mainly the potions that took some figuring out how the mechanics exactly worked, so I'd recommend putting in detailed descriptions for the potions, and since a tutorial was probably out of the question I'd give the player the option at the game's start to go to a "practice level" where they could play around with infinite troops/potions for as long as they want so they could figure everything out pretty quick
