A new build v0.05 is available right there.
Not much changed since previous progress update: added Heal spell; all spells now consume player’s mana; many small fixes and tweaks.
Changelog since v0.04:
- Added GUI: menus, options screen, HUD displaying player’s health and mana, etc.
- Experimental support for split-screen multiplayer
- Monsters drop mana (can’t be used by the player yet)
- A lot of other changes
