Reading the Construct 2 manual now.
I set myself up a fresh dropbox account, and I'm going to save my project on there, (so its always backed up!

), and I shouldn't imagine whatever I make to exceed 2gb anyway.
So once I get all versed up on Construct 2, I should think about designing something in more depth. Making/getting assets and all that to use.
Just need to come up with a relatively simple idea to practice with.
(Which is much harder than it seems because I can't bring myself just to do something as vanilla as a platformer or a brawler or something...)
EDIT: At the moment I'm thinking of doing some kind of action platformer that takes the idea of hitboxes from fighting games, and then adding in some crazy enemies that can spam projectiles or something, and then you could roll dodge and air dodge like in Super Smash Bros. Melee, and you'd have to time attacks and that.
Fast and fluid fighting. Walljumps. Light Stealth.
Dammit. Damn Mark of the Ninja giving me ideas. X_X
EDIT: Hmmm... designing the game around the enemies, rather than the player or the story and that.
Bit like Dark Souls really. Just cool, badass enemies with increasingly complicated patterns and strategies, and smarter AI. I should just make it like open-world or something, where you just explore and kick ass, and eventually unlock the final boss area, and he's super hard to beat, with multiple forms and that.
