Bullet Hell RPG

This Bullet Hell RPG was a team project in which Tommy Steenrod contributed all of the programming, and game design. Most of the gameplay systems were based on the game "Nuclear Throne".  The primary game systems include:

• Player Movement
• Item Pickups
• Enemy AI
• Randomized Levels & Item Drops
• Simple RPG Elements

Code Examples

///approach player
if (state = 1)
{
if (point_distance(obj_player.x,obj_player.y,x,y) > combatDistance)
