Question: What Game Engine Was Used to Create Pizza Tower?

Answer

"Pizza Tower" is an indie game that draws heavy inspiration from games like "Wario Land" was made using GameMaker Studio.

GameMaker Studio, by YoYo Games, is a popular choice among indie developers because it simplifies the game development process with its intuitive drag-and-drop interface and powerful scripting language, GML (GameMaker Language). It allows for quick prototyping and development, which can be particularly beneficial for small teams or solo developers. Here's a simple example of how you might move a character left and right with GameMaker Language:

// Create Event:
speed = 4;

// Step Event:
if (keyboard_check(vk_left)) {
    x -= speed;
}

if (keyboard_check(vk_right)) {
    x += speed;
}

In this code snippet, you have a speed variable defined in the Create Event which dictates how fast the character will move. Inside the Step Event, you check if the left or right keys are pressed; if they are, you decrease or increase the x position of the character, moving them left or right respectively. This is a fundamental example of character movement within GameMaker Studio.
