I'm back from my break.
Pretty much a lot of the outlined edits here, so I'll just briefly list what's been added. Also the gizmos are visible, in all their naked glory.
Foremost, the main menu. Nothing special - just a blank screen. with buttons. I like the lavender-purple-aqua color scheming that this is turning into. Play button goes to the first stage, which in this case is the practice room. Immediately afterwards, unpause and quit back. Second time around, there's a minor glitch in that the pause screen immediately shows since the stage never unpaused from last time. The missiles are allowed to hit the player, lowering their health (the detection on them is screwy - I tried box drawing where they're hitting, but apparently that isn't entirely working with the ranges they have - that's a fix for later. The second one will go and delete after hitting the wall to the left if it's allowed, but I didn't do that because I wanted to show the a second hit. After this, I went ahead and launched the fist towards the powerup.
The powerup base classes all pretty much work the same, they have some set modifiers for what they boost, and a duration. This one heals 5 health (the player has 5 total) and increases the player's movement speed for a set duration. After this, I just jump into the pit and die. Bit of pause-schenanigans, then back to menu. The attack-power increase is getting shelved, so besides health and mobility, there's pretty much only "shielding" left for now.
Where to from here? Well, crap. Guess I need to start adding in sound and that combo-list I put off. Nothing major for the sound, just listeners for various events. Need to fix those missiles as well so that they can be set into a prefab to launch on-demand in the training room. Guarding needs made. Then the practice rooftops need made.
