Well, some good news. The latest version of the power up patch is finally compatible with SA-1, and is installed on this game. This means it now has the following power ups:
Hammer Suit
Super Leaf
Tanooki Suit
Frog Suit
Superball Flower
Ice Flower
Mini Mushroom
Rocket Boots
Propeller Mushroom
Bubble Flower
Penguin Suit
Blue Shell
With the Cat Suit possibly coming in future. Pretty cool eh?
I've also now got blocks that shatter when hit with a hammer, boomerang, Mario in his shell form, a superball and statue Mario falling on them, as well as ones only passable as Mini Mario and water the latter can run on. The Superball flower can also be used to collect coins from afar.
Additionally, I've also added a great patch that adds platform collision for sprites, meaning sprites like enemies now interact with moving platforms, springs, etc. This has some... funny results:
(the grey platform falls if you stand on it directly, taking the Chuck and spring down with it)
It's absolutely insane, and it makes you almost question whether this is still Super Mario World you're playing. Then again, the levels and mechanics and sprites and effects and what not in general will probably make you question the same thing, since this is... basically a new game built on the same engine with only vague mechanical similarities left.
There's also a new map design in progress, various new levels (to even out the count) and a new game design expert on the testing team.
So yeah, expect to hear more (and perhaps see another demo) soon.
