Kirby's Epic Yarn, New Super Mario Bros. Wii, Noby Noby Boy, Incredible Crisis, most of the Game Room QLs, Wipeout, Again, Trauma Team, Silent Hill: Shattered Memories, Darkest of Days, Dragonball Evolution, and a ton more I can't remember offhand.
Also, watch the Kerbal Space Program quick look if you haven't. It's probably the funniest one ever made.
@Kodo_Beast: Honestly, though, health isn't the issue I have when playing puck, it's mana regen mid-game. Even with a bottle/wand I seem to be constantly short of mana - usually because I prioritise my blink before anything else, which just soaks up a load of gold...
Try Arcane -> Blink Dagger -> disassemble AB into Soul Booster -> late Bloodstone. One of the best build-ups with Arcane -> Soul Booster, and the option for Bloodstone later is a big plus.
For boots on Puck, I always go Tranquil Boots when I sidelane. It's essentially 525g for more regen than a Ring of Health (875g), +3 armor and comparable average movement speed to Phase Boots. They're pretty underrated on most heroes IMO.
Power Treads work really well though, especially if you go for Bottle and switch your stats around to get the most out of each charge (agility Treads -> use Bottle to heal, intelligence Treads -> cast spells, strength Treads -> taking damage).
For Lifestealer, you usually want an early Hand of Midas if you're jungling at level 1 (starting items Quelling Blade, Stout Shield and 1x Tango). If you're laning and have an ally that can create kills (allies like Ancient Apparition / Lina / Crystal Maiden), Orb of Venom can be very useful. Something like Stout Shield, 1-2 Iron Branches, 1-2 Tangos with starting gold -> Orb of Venom if you want to go that route.
Good items on him are (in no order):
Power Treads / Phase Boots
Desolator / Eye of Skadi / Satanic
Mjollnir (Mjollnir stacks with most, if not all attack modifiers in Dota 2, so you could go Desolator / Eye of Skadi / Satanic + Mjollnir with no problems)
Skull Basher -> Abyssal Blade
Sange and Yasha / Heaven's Balberd (Sange is just a great item on strength heroes for cheap health and damage)
Monkey King Bar
Shadow Blade (more of a fun item than anything)
Black King Bar
Scythe of Vyse / Orchid Malevolence (situational)
Drum of Endurance
Heart of Tarrasque
An example build would be Hand of Midas -> Power Treads -> Armlet -> Black King Bar -> Desolator -> Assault Curiass. Power Treads -> Armlet is a good place to start your build for most games. Gives you a lot of useful stats and comes in cheap parts. Don't be afraid to experiment though, there are a lot of very good builds on him to try out and practice.
You're gonna to need to play a lot of games, whether it's in Dota 2, LoL, HoN, etc. to understand how the game in general works.
Focus on one hero at a time in matchmaking games (~5 to 10 games in a row), if possible. Doesn't matter which hero you want to focus on as long as you enjoy playing it. Witch Doctor and Lich are pretty easy to pick up.
Follow the recommended items for a while. They're not always the optimal choice but it'll keep you focused on the action.
Try to have a Scroll of Teleportation in your inventory at all times.
Try and watch one game per play session, either from the Directed or Player Perspective camera.
Find other players around your skill level to play / talk about the game with. This is probably the best thing you can do to motivate yourself to improve and have fun.
