Released 2026-10-13. 2 updates since release, the newest 2026-10-13.
Newest update: Archery Refined (2026-10-13)
- Your bow now stands upright in your hand when drawn, and your arms no longer cut off at the wrists.
- Drawing the bowstring pulls straight back along the arrow instead of sliding sideways across the screen.
- All armor hides by default when you equip it—still protecting you, but letting you see your character clearly.
- Loot chests and defeated foes now open on the All tab so nothing gets missed.
- Trap Queen's health bar now shows her true 285 health instead of capping at 100.
Earlier update: Arcana Rebalanced (2026-10-13)

@makeriffic · 2026-10-13 · played 13 min: “I like the graphics and the details behind it! However, I already found some bug at the start of the game. My character is holding the bow in a wrong side. I understand the game is till a working progres. I like the flying dragon and the sleping one.”
- @razanur (maker) replied 2026-10-13: “my bad i have mostly been focused on the magic for this game but i'll fix the animations for the bow in no time.”
- @razanur (maker) replied 2026-10-13: “bow is fixed, will make it look prettier soon”
