Holy hell this is buggy :/ Clicking on planes sometimes does nothing, you can only turn the speaker off but not back on, planes move before you click the button to send a command, and clicking the "resign" button left the HUD up but the background went to the title screen.
You don't need a ton of Crypts to get Brilliant on 14. You just need the one on the high ground on the upper left to freeze the Ninja Champion, and you need to make sure that the other towers in the area can't hit him first. Then set up everything else as usual (you may need to Meteor a few ninja waves at the bottom gem pool due to the slow fire rate of the Crypt at the upper left).
Woah! I've got 2 achievements now, but the game doesn't remember my progress for some reason? This is on a second computer, don't know if that matters.
Pretty good! Can't actually think of anything that would improve it... therefore, 5/5 :) Except for a weird pausing bug... the miniboss music stopped working after frequent pauses in boss mode.
Excellent! My only complaint is the missile launcher's a little underpowered for its price. 5/5 nonetheless for outstanding gameplay, graphics, sound and duration.
Not impressed. Sound effects were buggy, the menu system inexplicably returns you to the default after several seconds (maybe I preselected a turret because I wanted to build one once I acquired enough energy, perhaps?!?) and sometimes refuses to select the building at all. 2/5.
