Yesterday I started experimenting with different game modes, and I'm going to try and make a run to get them in the game.
One mode is a one-life difficulty, which is exactly how it sounds. The player only has one life to beat the game. This wasn't hard to program at all, I just added a boolean so the player doesn't get "next level" or "reset level" prompts.
The other game mode is the mini-game I was talking about earlier this week. I as experimenting with it last night and I decided I'm going to try and include it. It's just a small addition that will occur after every few levels or so. Specifically after the player collects a part of their "brain".
The only hard part I think will be getting the minigame to load the correct level after the minigame is completed. I'll probably just have to manually enter the level every scene. Oh well, there will only be a few of these events so nothing to worry about.
I should also probably make a transition to the minigames. For that matter, a transition between levels other than a menu. Maybe a fade to white? I will have to think more on it.
