Upstairs

Upstairs is a fresh look on Tower Defense genre. Being on a small platform, the player needs to build a line of defense against oncoming threats. However, the main target of the monsters is the player himself.
- Build and upgrade towers wisely, because you are limited in the number of upgrades

- Dodge waves of enemies while your towers deal with them

- Several unique towers with different uses and interesting abilities

- Multiple enemies each of them has its own task on the field

- Unique gameplay and endless arcade mode with multiple difficulty levels and maps

The game is a kind of Downstairs spin-off and partially uses assets from it.
