Thanks for those who gave me initial feedback. I got a lot of great stuff, so here is what I’ve done in the new patch (0.1.2)

1. You can mute the music by pressing M.

2. You can use the mousewheel in either direction to switch spells. Pressing 1 and 2 also switches weapons.

3. Some changes with in-game text.

4. The boss is now a bit easier. The Silver Construct has a longer wind-up time before his lightning attack. His melee also does less damage. He speed was also slightly reduced. His minions also spawn slightly less frequently.

5. Fixed a bug where health/mana cubes would not respawn during the boss.

6. The Red Construct’s shield now does nothing, since its just made of. The boss’s shield hitbox now works properly.

7. Sprinting now has an initial cost of 1 mana to prevent some abuse.

8. The boss’s lightning arrow model no longer goes through obstacles.

9. The crosshair now accurately reflects where your ice blast will go.

…and I think that’s it. Again, thanks to all who gave me feedback.
