About

Under Construction Ext

Features
Read full description

This is a construction site. It is a game to fill all the stones in the hole. The bulldozer can only push the stone forward. Operate the bulldozer well and move the stone to the hole position. To move the bulldozer, drag the movement path with your finger from the position of the bulldozer. The route is displayed as a red line, so release the finger and the bulldozer will start moving. If you notice a mistake before releasing your finger, it will be canceled if you do not move your finger for 3 seconds.

This is an engaging puzzle game where you control a red block by swiping up, down, left, and right to reach the goal while avoiding traps. The challenge lies in the ground: white tiles collapse after one step, while blue tiles can be stepped on twice. As you advance, you must collect small rotating red cubes to unlock the portal to the next level. The real challenge is earning a three-star rating. Not only do you need to collect all the cubes, but you also have to collapse every tile. Once completed, you'll earn a special pixel badge. There's no time limit, so you can think at your own pace and demonstrate your strategy and wisdom. Come and experience this journey that tests your mind and skills!
