About this game

IQ Under Construction

When we said “we're building a game for fun,” we didn't think it would turn out like this.

IQ Under Construction is an escalating frenzy where you and your friends are connected by a mysterious energy (don't ask how it works — we don't fully understand it ourselves). The main thing is not to stray too far from each other, otherwise... ready, set, go — back to the beginning!

You start at the bottom and climb higher and higher, overcoming clever obstacles, jumping over dangerous structures, and screaming at each other in voice chat in a panic (if you want to, of course). This game is like friendship: if someone decides to go it alone, it's game over for everyone.

🔍 What's inside?

🚀 Vertical climbing with increasing levels of difficulty

At first, everything is easy. Almost cute. But with each new location, the structure becomes more vicious. Jumping platforms, disappearing blocks, traps that were clearly invented by someone who was awake all night with no conscience.

🔗 Connection between players

You can't run around as you please — the game world is against it. If someone flies too far, the whole team flies back. Fun, right?

🌆 Different locations, but the same vicious logic

The world is one, but the levels in it are completely different. Architecture, pace, traps — everything is constantly changing so that you don't relax and think, “Well, now it will definitely be easier.”

👥 Alone or with friends

Want some peace and quiet? Play alone. Want chaos, laughter, screams, and moral support? The game supports up to 4 players online. The main thing is to remember: if one falls, everyone falls.

🎨 A style that's easy on the eyes (but maybe not on the nerves)

Colorful scenes, clear shapes, everything moves, shines, and teases you. Does the platform look simple? Suspicious. Check twice.

🎵 Music to keep you sane

The soundtrack changes with you. Calm moments sound pleasant... and then the platform with millimeter jumps begins, and the sound abruptly ceases to be background noise.
