Not sure why people are having such trouble. It took a couple runs, but each run doesn't take that long. I defeated a dragon with Excalibur, Astral Armor and an Elixir.
Ah, nothing like that sense of satisfaction when you buy the 800th Newspaper and you know you're that much closer to getting all the... what do you MEAN they go to 1100 now?
Since the tree is an active floor, why not make it so that harvesting from the tree also increases the multiplier? The 5 jellies you get from the button are useless, but the fact that it increases the multiplier basically means spending any active time on the tree is pretty useless.
Anyone else find it weird that when you have 500 oil companies and 400 newspapers it costs half as much to get a new oil company? Those are some damn expensive newspapers.
Not sure if this has been mentioned, but when I switch to the "Upgrades" screen it almost always shows a very large scroll bar, like what you would see if you're seeing almost everything on the menu. When I click and drag, it zooms straight down to the bottom of the upgrades menu. Minor annoyance, nothing serious.
I think the last achievement is actually "Score 2000 points" and not "Get 2000 kills". The 2x score bonus seems to make this easier (even better when you have 2 2x score bonuses active at the same time).
Great game. It would be nice if reaching max level unlocked something special, like an additional challenge (2 of each boss all at once?), an additional upgrade level for your support/abilities, etc. The "Congratulations" screen is nice, but doesn't really reward you for completing everything.
As intrinsics says - replay value should be up. I suggest a "time bonus" for replaying levels. The more time/health you have left at the end, the more money you make.
My final line-up was (left to right): 3 rows of spikes, 1 row of knights, 4 rows of archers, cycled through cannon-shotgun-arrows-iceball. The extra line of archers is enough to take out the ghosts with no issue, knights are basically like walls but they do some damage - they will need occasional replacement, but the extra line of archers also helps keep enemies off of them.
All of the above maxed (except the iceball slow portion).
Okay, as a tip for 100% completion - towers can be affixed with BOTH grenades and mines. Had myself stuck at 94% for some time before I figured that out.
How about a list of what makes 100% completion? I have everything secured, everything upgraded, purchased all upgrades and weapons, and still only have 94%. Do I need to do all the rambles? Finding additional hidden locations doesn't seem to be causing the % to go up. Do all the weapons need to be at top level? I'm confused.
I don't quite understand the reasoning behind the varying sale prices. If you had a place to store cargo outside of the ship, so that you could hold off on selling it for a day or two to see if the price improves, that would work. Or if the loot was more of the "commodity" variety (i.e. you loot 20kg of rice which is currently selling at 5 gold/kg), then you could hold on to it to see if the sale price went up the next day. The way it is, I'm just annoyed when the sale price is red and happy when it's green, but I still end up selling everything each day.
One minor issue - if you get them up to speed and give them a big jump, they sometimes explode even though they're going to land on the road (I assume it's an air timer thing for when they fall off the side).
Cool concept, and seems to work well. I saw the comment where you said you think adding features after the deadline wouldn't be "in the spirit of the event". While I can see that viewpoint, you have some potential to turn this into a pretty awesome game with additional features. Maybe you should look at it from the viewpoint of "The event is a great way to jumpstart a project that could turn into something awesome". I think a lot of people would agree that this game is worth some more time investment.
Supplies!
