Damnit, if you'd told me that I needed to pay to do the missions, I wouldn't have spent all my money in the shop! *grindy-grind to earn enough to do the next damned mission*
Given that all the puzzles can quickly be solved by trial and error because of the excessive hints from the white numbers, the hard badge is very generous. It should really be a medium.
@JSilvis: Last level works for me. You've probably made a mistake, even though you checked it. Has every one of the hint numbers turned white? Any black ones indicate where your mistake is.
The numbers turning white are a disaster. The number changes colour as soon as you have the relevant line of squares in the right place, which gives you enough information to quickly solve the puzzle by trial and error, rather than by working it out.
Most of the levels are pretty easy: could definitely use a few harder ones. And the controls get a bit confusing when you use the warp squares, as you can't just drag any more but have to release the mouse button, move and start dragging again.
The 4x4 and 5x5 multiplication puzzles are too easy because there's only one way of making each possible target: 2=1x2 3=1x3 4=1x4 (2x2 not possible) 5=1x5 6=2x3 8=2x4 10=2x5 12=3x4 20=4x5. The addition puzzles are more interesting because, e.g., 5=1+4=2+3 so there's more than one possibility.
This quickly becomes annoying as there's too little leeway between making a platform that's too high to jump onto and one that's too low to let you jump to where you're trying to go. On levels that require multiple platforms to be placed, this just turns into a tedious restart-fest.
The bait and switch on how to win the game is kind of annoying. First, it's "Rescue all ten princesses." Then, it's "Get to 25,000m." Then, it's "Oh, by the way, you need to have finished all the quests or you insta-die at 25,000m." Then, it's "Oh, and once you've finished all the quests and got to 25,000m, you also have to defeat the boss." I thought I'd won three times before it actually happened.
The game mechanics make no sense to me. I just don't see how the rocket and the tower and the monsters physically relate to one another. I understand what I need to do to get points and stuff. But it just doesn't make sense.
Meh. The first two attempts, I died. The third attempt, I won in 44hrs. But I only got 9/20 achievements, essentially because I won too quickly without, say, surviving day 2 or 3 or having time to upgrade my fort much. Either I was very lucky or this game is much easier than its developers think it is. That, or they picked achievements knowing that you'd have to go deliberately slowly to get them. What's the point of that?
The puzzles are insanely easy at the start and there's far too much time wasted between levels. I came here to play the puzzles, not to watch the same flashy graphic again and again. Sure, nice graphics are nice, but the primary purpose should be the puzzling. Also, big mistake: the numbers turning white when a row/column is correct lets the player cheat. If there are only two or three ways a row/column could be done, you can just try them and see which makes the numbers go white. The number should go white whenever the constraint has been satisfied, e.g., whenever you have a block of three and a block of two in a "3 2" row, regardless of whether you have the correct three and two.
Well, if you're lucky and only lifeform beta survives, it doesn't shoot at you and the game gets very boring. Just upgrade your weapons a couple of times, zig-zag across the middle of the screen and upgrade the engines to move faster and shoot more stuff.
