UPDATE: OK, sure enough; looked up a guide, and the "solution" to this level is to abuse the way the game finds pixels to colour shift to magically shift a region isolated from the one you clicked... Basically, click, hope it works, if not, restart and click again, wait for RNG to help out.
I don't know if that's intended or not, but it's pretty poor design either way.
Hang on, isn't lvl 8 impossible?
There are 5 colours of pixels. Each click can change 1 region of one colour to one other colour, and we get 4 clicks. This means, to win the level, each click must completely eliminate a colour to win; that's fine, that's the puzzle.
But here, every colour has at least 2 separate regions to start. While changes can combine regions down the line, that very first click cannot, no matter what, eliminate a colour, and no click can eliminate two colours. What gives?
Following on, looks like it's fairly common, but normally if you scroll the area where the gap should be far enough off screen, it comes back; in this area, it wasn't big enough to do that, so I was stuck.
So, uhh, I don't know if this intentional, but I'm stuck. Went into a section, came back to find out it had closed off behind me. This isn't a large, complicated area where I may just be lost, it's literally a short run, straight but for two corners, 22 blocks long, all fits on the screen at once.
Oh no, loud music! Options, turn off the music... ahhh, relief. Great. Click to go back to the main menu, and... oh. Oh, it resets the options, turning the music back on. Greeeeeat.
For level 7, just spin the wheel for a while, wonder why nothing's happening, click the hint, click the second hint, spin some more, read the comments, spin for ages, get frustrated, leave a comment complaining about the level, rate 1 star, and close the game. It's easy!
There's a weird bug with the game; as the level goes on, after a while it starts freezing a bit, and then slowing down and dropping frame, going quickly from "noticeable" to "completely unplayable"... and I'm not 100% sure why. It happens quicker if you try to kill and collect everything, but apart from that, stumped.
It's not caused by bullets or killing enemies, I tried not firing at all and it didn't happen. It's not caused by number of enemies, because it still happens if I'm clearing everything. It's not just caused by going right because, by ignoring everything, I managed to get to the end without issue. Best I can figure it's either number of enemies spawned (with killed enemies not getting properly "cleaned up" and so still contributing to slowdown), or just time by itself, but not sure why that would happen.
Also, the last red gem at the bottom-right corner can't be picked up due to an invisible wall, and PLEASE ADD A MUTE BUTTON FOR THE LOVE OF FLIP.
Why are the planets deadly? This only makes sense is if the planets are closer than the asteroids, which means either the planets are tiny or the ship is huge. It's also inconsistent: the purple planet *doesn't* kill the player. If you really want this, you need to make this clearer. Put a red border around the planets, darken the background/asteroids to make them less important.
The ship has too much speed/momentum, it's too easy to accidentally hit the planets. It's also weird spending most of the time being shot by enemies really far away; I'd advise reducing the speed of everything by about 20/30%, and halving (at least) the range enemies shoot. The speedup power is essentially worthless; moving faster just makes it easier to get into trouble. I'd trade that for an autofire powerup so I wasn't having to constantly click the mouse. The health pickups do almost nothing to increase survivability, need more or better ones.
OK, I dig it. It would be helpful if, when you hit your cash limit, you could set the game to (rather than just stop production) either start stockpiling items instead of selling them, or to auto-buy workers.
"Collect 20 Coins to win."
Some of you may be wondering what happens when you get all 20 coins, and "win". The answer is... nothing. Nothing happens. The coin count resets to zero. You keep playing.
Actually, hang on, no; it's just that, if you get XBox 1 to 926. it's output of money and skill drops to zero, naturally a huge. At this kind of level, the income from training and jobs in essentially negligible.
One last bug, cascading off the last one: XBox 1 can only be upgraded to 926, rather than capping at 1,000 like everything else (at which point your money and skill point cap at 100.000 Centillion and 2300362000.000 Centillion respectively).
Game breaking bug time: the development time has no lower limit (in the current version), and combined with how awesome the Dreamcast is, you can get enough enough cash to reduce wait time to 0, meaning absurd income.
OK, what's going on with that list of platforms? I mean, it's a little strange anyway... quite heavily weighted early on to obscure systems, whilst completely skipping more famous ones like the MSX, Master System, or the goddamn Atari 2600... But then you get to a certain point, and it just gets weird.
You get the Station (which apparently sits between the Famicom and SNES, which is an off pair in themselves... with the JP name for one, the US/EU for the other?), the Sony Playstation (which sits just after the Sega Saturn and the Victor V, which are the same thing), the Sony PS One, and the Sony PSX (which is apparently more expensive to develop for than the Playstation 2).
I don't know how to break it to you, but... those are all the same thing. They're all the PS1. At least, I assume this is what "the Station" is, there's no actual system by that name that I'm aware of, but either way you've got it listed at least 3 times..
