Tactical Nexus

Here is an excerpt from Tactical Nexus's Steam description:

What lies underneath the cute and colorful pixel-art RPG facade is nothing less than one of the world’s most difficult hand-crafted puzzle games. A combination of resource management, logic puzzles, and tantalizing power-ups are your tools to climb up the enemy-riddled floors of each Magic Tower!

Tactical Nexus is a single-player Magic Tower game inspired by the classic game “Tower of the Sorcerer,” combining magic, power-ups, and multitudes of monstrous foes to defeat and delve deeper into each Tower!

This is our Puzzle RPG that can be played for 10,000 hours. A resource management game with overwhelming “quality-of-life functionality" to conquer puzzles with overwhelmingly high difficulty. One of the world's top 3 indie games in terms of average play time.

The base game includes twelve Magic Towers, with dozens of hand-crafted floors to navigate, explore, and grow your power! The base game can reward you for hundreds of hours of gameplay with continued meta progress that allows you to take another step further!

There are no random elements used, no procedural generation, and to advance you’ll need to find the best way through your enemies and reach the ‘Clear’ tile. Every tower will remain the same each time you play it, yet you can grow stronger!
