Instructions
Stack the highest tower by aligning blocks with at least 50% accuracy! The horizontal and vertical speed increases will make the level harder over time. Your tower height will also be recorded.

Description
Inspired by classic tower stack mobile games, I wanted to create an alternative version of it using a simple horizontal “crane”, with pressure given to the player from its increased speed over time. As the player begins to stack a higher tower, original blocks also begin to slide downwards, creating more time pressure for players. I also wanted to explore creating minimalistic graphics for a challenging, interactive game.
