About this game

This is a port of the PC game. No ads, no in-app payments, no online required.

A short relaxing incremental game disguised as a tower defense, but enemies can’t reach your walls. Thanks to lava.
Enemies constantly run toward your walls. You buy defenders, upgrade production, and watch the waves grow.
But they can’t reach you. There is a river of lava at the end. Every enemy falls into it. Every time.
This is a tower defense where you already won. Sit back, relax, and enjoy the lava.
A short relaxing tower defense idle game, but you can't fail. Thanks to lava

Totally worth 3 bucks for a game with zero ads! It's (obviously) a direct port from PC (corroborated by the dev), so some of the functions are a bit wonky and buttons too small. Still, it's a chill incremental game perfect for toilet time and to let run while I do other things. Edit: the update on June 13th improved touchscreen compatibility by adding long presses for right-clicks and an attack offset to see around your finger... It takes a bit of getting used to, but it definitely helps.

A great time waster and it accomplishes its task excellently. I am not sad at all for buying the game, it was short lived but kept my mind preoccupied. my only complaint, and reason for the 4 star, is its length. once you finish, that is it. there is very little replayability to this game which is quite a bummer because it seems like it has endless potential.

Decent game for the price. Found myself completing it within 15-20 hours of passive play. The fun part of the game, watching dozens of creeps and minions dying to hundreds of little projectiles, is the highlight. Progression revolves around prestiging about 3-4 times. The descriptions on abilities tend to be a bit vague as well. I'd say there is little replay value once completing the game besides optimizing your run even further. It's great to play alongside other games that have downtime.
