Hydra Slayer v18.3
Yet another bugfix update! Fixed the bug with help not displaying, crash when examining shadow hydras, and lacking music (due to the lack of a DLL file).
You face a 9-headed hydra. Your sword cuts 5 heads in each swipe (never less), which kills a 5-headed hydra, but a larger one will regrow 2 heads after each swipe. Your scythe cuts exactly 7, but 10 grow back if the hydra lives. Can you kill the hydra? Or better to explore to find more arms first?

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Another bugfix update. This fixes Titans not using up items correctly, Atlantean achievements, and the Resurrection achievement triggered with Twins. Have fun!
This is mostly a bugfix update. It uses a newer version of the NotEye engine. It should fix the problem with mouse clicks not targetting the correct tile, some bugs with mini-map, and other minor bugs. Have fun!
A small update should fix the font rendering issue on Linux.
Update 18.0a fixes a problem which prevented some high scores from being uploaded to Steam. The bug affected most of the games with very good scores, and thus the leaderboards looked as if mostly nobody has ever beaten the second boss. View your local scores ("View achievements and the Hall of Fame" in the menu) to send them to Steam. Unfortunately, your local scores will not be uploaded to the "no potions of life" leaderboards if you later used a Potion of Life in the given game. Also share your game logs or strategies on the forum! http://steamcommunity.com/app/432380/discussions/0/371918937
