I've been messing with a platformer in Construct, the plan is to set it up so that I just draw a bunch of islands on pieces of paper and then scan them in and explore them in a game. Some of the slopes don't work too well with the default platform setup and I'm still on the very basics of getting shit done/havent started thinking about actual game design or enemies at all yet. Here's my practice level if anyone's interested: http://www.mediafire.com/?22l1d8k8c6319ls z to jump arrows to move
Wait, are you making algorithms to automatically set the map up to be playable or are you going to still have to fiddle around with invisible platforms etc after you scan it in? I really like the idea of "draw a map, game let's you play it", if that's what you're doing! Otherwise, hand drawn platformer sounds good because every other platformer is mario or megaman rips/edits and that's visually boring.
Might I suggest setting the hearts Horizontal instead of Vertical? it seems a lot more obstructive like that.
ps: is the main character a girl? looks like they've got pigtails so i assume yes?
