First Update — Dungeon of Zolthan Steam update #477890

I made an update to the game, and here is the list of changes. Double tapping left/right to dash can now be toggled on or off. It defaults to ON for previous players and OFF for new players. A Mac version has been added. The text for the dash powerup now mentions the dash key set in the control settings. Invulnerability time has been reduced for all enemies, including bosses. The first boss has 2 less health, a slightly lower starting speed, but a much higher max speed. A save point has been added near the first powerup. The main music loop has been extended and the final boss music has been changed.
