Either adjust size, spacing or jump height/logic. * Maybe player should have three lives - shown as little red hearts in top right corner. --------------------- Interface/graphics: * Show instructions on screen at start. * Maybe elephant should face the last direction it moved. -------------- Powerup ideas: * A powerup that removes all nearby platforms and give score for them. * Maybe make a disco powerup that changes light, colors or visuals somehow. * Consider platforms that increase or decrease the size/weight of the character. * Or maybe just a platform with a piece of cake on it, and when player lands there he gets 10 points and swells up (no gameplay side effects) for 5 seconds. Could actually be all kinds of funny pickups like that. * Different hats that the player will wear until a new one is picked up? ---------- Gameplay: * Consider difficulty ramping. More red platforms? * Make sure red platforms never fully block the way. Platforms have row and column id's to pattern match against. ----------- Theming: * Consider possible player character. * A frog? A kangaroo? A spring? A tennisball? A rabbit? A two-headed squirrel? Something on a pogostick? * A Rick Dangerous finding treasures on the platforms? * A Pirate Ship finding bounty on platforms? Maybe beats platforms with less strength than they have? * A cat eating sushi on each platform? * A princess saving animals on every tenth platform? * Maybe all those characters, each triggered by a powerup until a new one is picked up. * Maybe new mode unlocked per 200 platforms or so?
