About this game

The secrets and treasures of ancient civilizations have long eluded the Astra Hunters: a guild of explorers-for-hire tasked with uncovering the world's greatest riches. And Zosma is the greatest Astra Hunter of them all! Or at least he wishes, were he not ranked dead last as always.
What seems like a routine attempt to uncover more about Zosma's favorite adventuring ground becomes the beginning of a grand adventure as he plummets for miles to what should have been certain death! With no way up back to the surface except through the daunting Crescent Moon Tower, Zosma may just find his greatest discoveries ever... and get some help from a mysterious animal companion along the way!
Unleash the power of teamwork, collect valuables, and solve the mystery of the Crescent Moon Tower in this RPG adventure!
Astra Hunter Zosma is a short treasure-hunting RPG with a focus on dungeon exploration and a blossoming friendship between a buddy duo! Collect treasure as you climb the Crescent Moon Tower to help make Zosma the greatest Astra Hunter upon his return home!

Patch NotesOfficial
Version 1.0.6
Hello all! Astra Hunter Zosma has been updated to Version 1.0.6. This is a minor patch that makes the following changes: Fixed a bug where you can permanently lose the ship in Chapter 5 if you lose in a normal battle under specific circumstances. Relocated the lever and the NPC that moves the ship in the harbor to the east side of the map. You may now talk to this NPC to retrieve the ship if it is still missing.Read full article on Community Announcements (Torch60)Patch NotesOfficial
Version 1.0.5
Hello all! Astra Hunter Zosma has been updated to Version 1.0.5. This is a minor patch that makes the following changes: BALANCE CHANGES Box Botherer X is now weak to fire like its normal counterpart. BUG FIXES: The AP and Chain Counter now clear from the screen at the end of battle. Made the requirements to "Create a Chain of X or more" read as "Create a Physical/Magic Chain of X or more" in boss fights that include the Protect mechanic, as items were not intended to fulfill it. Fixed a bug where no map music would play if you fell in battle and your last save point was on 2F. Fixed some wall tiles being walkable in the final area. Minor text fixes.Read full article on Community Announcements (Torch60)Patch NotesOfficial
Version 1.0.4
Hello all! Astra Hunter Zosma has been updated to Version 1.0.4. This is a minor patch that makes the following changes: NOTABLE CHANGES: Enemies will now use normal Attack animations that are more consistent with their appearance. For example, enemies holding swords will use slashing animations and those with staves or unarmed will use striking animations. The enemy skills Double Cut and Triple Cut now have equivalent skills Double Strike and Triple Strike and are used by enemies without bladed weapons. In Chapter 1, the Least Important Character in the Game now reminds you to equip new weapons and armor that you buy or find, making them slightly more important (but still the least important). Removed the unused "Neutral" element from the Status menu, which nothing in the game granted bonuses to. BUG FIXES: Fixed a bug where elemental resistances would not add correctly if granted from multiple sources. For example, having the Companion wear an Element Ring while also having points invested in Element Resist should now grant the correct bonus. Fixed some enemy attacks not being considered physical attacks when they should be. Fixed several weapons and armors: Magic Foil and Dragon Hood should now increase stats by their intended amounts. Steel Blade should no longer reduce Zosma's SPD by 8. Minor graphical fixes for some field sprites.Read full article on Community Announcements (Torch60)Patch NotesOfficial
Version 1.0.3
Hello all! Astra Hunter Zosma has been updated to Version 1.0.3. This is a minor patch that makes the following changes: The boss of Expanding Void Part 6 should now have the correct battle background. Changed the formula for the amount of SP restored by Focus Shards. They will now restore 1 + (Chain Bonus% / 20) SP. This was changed due to a bug with the previous formula, where the amount restored would only be affected by Item Chains and ignored all other Chain types. It should no longer be possible to get the blocks stuck on the blue mushroom puzzle in Chapter 2 and box yourself in. Minor text fixes. Minor mapping fixes.Read full article on Community Announcements (Torch60)Patch NotesOfficial
Version 1.0.2
Astra Hunter Zosma has been updated to Version 1.0.2. This is a minor patch that makes the following changes: Fixed some previous cutscene elements appearing if you backtracked at certain points in the story. Fixed an issue where the wrong BGM would play if you backtracked from 39F. Fixed a boss fight in Chapter 5 having the wrong battle theme under specific circumstances. Certain endgame equipment should no longer be sellable. Made Treasure Note 21 a little more clear.Read full article on Community Announcements (Torch60)
