About this game

Step into the secret civilization built within the walls of a forgotten attic, now locked in a state of endless war. Brave critters have forged powerful war machines from scavenged scrap, powered by mysterious spinning wheels. But a bitter fight brews between the peace-seeking Wheel Alliance and the ruthless Order of the Rusty Trap – a deadly enemy who wield dark magic and seek total domination through relentless battle.

In Underbite: Rat Rumble Idle War, you command the Alliance's front line fight. Your primary weapon? A chaotic, wheel-powered war machine. Spin the wheels to generate loyal hamster fighters and deploy them from your machine into the heart of battle against waves of vicious enemy rats and menacing enemy bosses controlled by the Rusty Trap. Prepare for constant war!

This is an idle strategy game where survival depends on your ingenuity in the ongoing fight. You must constantly upgrade your war machine by stacking and merging its core components – the battle wheels. Faster wheel spinning means faster troop deployment from your machine, stronger fighters, and a better chance to push back the tide of the enemy in this desperate war.

Manage your resources, adapt your machine's build for each battle, and lead your rodent forces to victory against the enemy in this fight for control of the attic warzone.

Key Features:
▶ Immersive Rodent World: Discover the hidden conflict and lore of the attic's warring factions engaged in total war.
▶ Wheel-Powered Combat: Master the unique mechanic of spinning wheels to fuel your war effort and power your machine.
▶ Strategic Machine Upgrades: Build and evolve your war machine through stacking and merging wheels for better battle performance.
▶ Lead Fearless Warriors: Command hamster troops against hordes of enemy rats and powerful faction bosses in strategic battle.
▶ Fight for the Alliance: Defend against the enemy Rusty Trap's invasion in tactical idle battles, leading the fight with your machine.

The fate of the attic rests on your machine in this war.
Harness the power of the wheels. Command your fighters. Crush the enemy. Win the battle.

Game isn't bad, but after going thru nearly 30 levels it's become stale. I'm able to do almost every single level the exact same way with no need for tactics to gain my 3 stars. I can continue upgrading everything, but the rest of the features appear to be locked. I can consider re-rating at a later date if tactics can be changed or if new content is added.

This is a really cute puzzle type game. There's still some bugs to be worked out. when you don't complete the level with a score of 100 sometimes it shows up as fully completed. So you can't go back and replay the level for the missing prizes. I'm very interested to see where the developers take this game.

1 enemy can push back your entire characters back? no matter how many are on the field they all get pushed back and can't attack fast enough. the game is meant for you to lose after a certain level. don't play it
