I guess I should set base default loudness off of a worst case scenario where the player's maxed out on their PC's speakers to minimize the risk of hurting someone's ears.
Yeah, animations are super awful place holders right now since I haven't worked out a decent workflow yet. I'd planned to have proper animations made in Blender and improved models as the big new thing for this DD, but sadly it's taking me longer to figure out the implementation than I'd hoped.
The lack of sprinting while airborne is an oversight on my part. Oops.
What makes you want a higher default movement speed?
You start the real game/the enemies's AI by selecting a different game mode than "punching bags" under "enemy mode" in the mode select menu. The top left menu button should switch to "Begin Waves" instead of "Begin Practice" or "Resume" to show it. If you mean "how do I start a real level", then sorry, there's just waves of barely-animated enemies in the one map.
You can skip the quitting animation by clicking "quit game" again. The animation is basically just a fancier "are you sure" popup with a timer. Although I ought to actually explain that somewhere in the game.
Oh, and thank you for playing!
