Desperately needs a preloader. It would be better it the story was spread throughout the game, instead of a wall of text at the start. You should replace the plain sky tiles with a decent background, and put a texture on the yellow blocks.
Armoured creeps can soak 10% of their max hit points every time they get shot. If your turret does 10 damage and the armoured creep has 100+ hitpoints, you can't hurt it at all .... it's not invincible, but you need a bigger gun.
You need to reset the score after each game, and not add it to the previous game's score. I think an escalating difficulty would be good - the game starts too hard. Start the game with fewer colours, or a longer guiding line, or more shots between each new row, and increase the difficulty as the game progresses.
Needs some more work. Hotspots for placing are sometimes hard to find. It can be impossible to play if the dominoes have gone in a loop or near the edge of the table; you can pick up the dominoe then the game jams because you can't place it or drop it, and you have to restart. Sometimes dominoes are played the wrong way round. AI is very weak. That animation of the man with cardboard arms slapping the table doesn't look good, or fit with the style of the game.
It's a really good concept with a good theme. The early levels need to be simpler. A really small island to demonstrate the concepts. There should be a reset level button. The quit level button is hard to find, hidden in the instructions - what's it doing in there?
Can't see me using it much, but we can point towards this whenever someone requests a 'developers only' room. Those links at the top need tidying up. Good stuff, keep it up.
I could fix the 1.9 billion bug, but it would kill everyone's saves. I don't think that will make you guys very happy (I really wasn't expecting anyone to get past 1.9B when I made this).
I'm getting asked frequently what the requirements are for the trophies.
Visit the same tile at least 10/20/50/250/1000 times.
Total moves of 400/800/1136/4000/20000.
You also get an award for completing your first maze, and for sharing a maze.
Good luck with the 20k one, only two people have managed it so far.
I think to get a decent 'no leaks' score you need to do some juggling. Lots of juggling. Even with the best maze there's a limit because creeps' health increases faster than your income. Measure - nice maze - looks like one of mine :)
How strange. It says that this game is by Brock White, but the other 11 games you've uploaded today are by different authors. Do you honestly think no one will find out?
Measure, the game saves a .sol file to your hard disk. If you use a different computer, your save won't be there. That's the only thing I can think of...
