I played Space Disorder. I liked it a lot. Any info you can give about it since the description on the site isn't in english?
What's the deal with the coin things? Are they worth more if you collect them in a row or closer to the top of the screen or what? And at what point do I get extends? I wasn't paying attention but I think I got a couple on my way to 30000
The description on the site is both in english and portuguese, you've got portuguese on the left and english on the right.
But there's no info about scoring on the game

There's some info on the readme.txt file comes together with the game.
The coins raise value as you get them. The 1st coin will give 1 point, the 2nd 2 points, and so on. Their value will reset only when you die, so no need to get them all. Get 100 coins, and you get an extra live (And the amount of coins needed for an extra live raises a little). The game gives you lots of lives early on, it's possible to get like 3 extends in less than 3 seconds... guess that's another nod to Compile
I must admit I don't remember with how many points you get your first extend (I've finished coding this game like 4-5 years ago), but it's nearly random numbers like in Compile games. At every new extend you get, the next one will need more points to be awarded (The game also will inform you how many points you'll need)
I liked the game. I would have liked the enemy formations to have moved a little faster and been a little more aggressive. I also think the different weapons could have had more of a defined purpose. Then again, the same could have been said for any Compile developed game.
Really? How far did you get? Most people usually complain that the game gets brutally difficulty very early (a little before the 1st bosses - stage 5 - the enemies will already be very agressive... reach level 20 and you'll be in hell

).
About using Z... yeah, I would make the control setup different if I made the game today. I wouldn't even dare touching the source code of it again, because most of it is a big mess (Nowadays I am a more organized programmer

), and it's something I consider "done", and I am working on new stuff now.
And I partially agree with the weapons. The rear shot is useful in some spots, the Triple shot is by far the best weapon in the game*, and laser and twin laser are basically the same thing (Normal laser has the same power of the twin laser).
*There's a secret weapon on the game which is powerful enough to destroy bosses in less than 5 seconds. Also there is a way to acquire options, which will make your ship a lot stronger too. Secret Weapon + 2 options is more deadly than a fully powered up X2 ship... problem is that when you die, you will *REALLY* miss all that power
