Indie Engine at the start was going to be a towerfall ascension engine for gms 2, has turned into its own engine. Players are not bound by 8 way directional aiming, there is no aim assist after arrows are fired. Players do have the option to fire a tracer arrow or spear depending on what hero they select. This engine supports local multiplayer, and has the ability to extend away from the normal tower defence single player style of game play made for the example. The engine lets you interact with the environment by the use of jump pads(drums) and fire can be used to set arrows on fire which hurt enemies if the run into fire arrows on the ground.
