Idle Invasion

A solo 75-second encounter inside Unnamed Space Idle. Pick Knife, Magic Wand or Garlic, defend your existing ship against increasingly large animated bat waves, and choose an upgrade after every five bat kills. Retreat, ship defeat or navigating to another sector ends the encounter; upgrades last for that encounter. Bat kills do not grant permanent resources.

Vampire Survivors supplies its actual weapon statistics, level-up changes, enemy characteristics and animated bat sprites, decoded directly into memory from your own installed copy. Both games are required. Your original Unnamed Space Idle executable, ship, scenes and combat remain the host; no game content is bundled.

Version 0.1.3 passed two two-minute Melty install and gameplay tests on this PC, including loading, companion content, bat spawning, weapon damage, an earned upgrade and completion. The screenshots and clip show this version running in Unnamed Space Idle.
