Towerix91 is a tower defense game in the style of PC games from the late 80s and early 90s. A warm color palette, soft CRT monitor effect, and an interface reminiscent of old operating systems create the atmosphere of a classic strategy game running on a vintage computer.
Place towers on the walls, manage resources, and fend off waves of enemies. The game features a skill tree that upgrades different types of towers and unlocks new tactical possibilities.
Crystals serve as upgrade points: they are earned by destroying enemies, but are only credited upon successful completion of a wave. The more powerful the upgrade, the rarer the crystals required to unlock it.
This is an old-school tower defense game where progress is built on calculation, efficiency, and thoughtful defense development.
