Christ That's Hard!
I had to skip nearly all of the levels at the end because of how steep the difficulty curve was. I'd say this is mainly because I didn't have a good idea of the teacher's line of sight. The green triangle was nice but the teacher could see outside of it, which I didn't like. If the teacher's line of sight is going to be bigger, make the green triangle bigger! I felt like I really got jipped by that later in the game. Other than that I really liked the gameplay and felt this is the best stealth game (series) I've ever seen on Newgrounds!
Sidequests, or 'extra credit' would be cool, and the whole thing with waiting for distractions or using Melanie should really be expanded on! More things like that or usable items, distractions, etc. would be cool. Maybe a paper airplane? Maybe having to figure out which students are rats and which ones aren't, with some students having a limited line of sight as well? There's SO much to expand on here, yet the concept is so simple!
The graphics, while dots, stayed true to the primitive style of the earlier versions, which I won't criticize, as I see this was a stylistic decision, based off of how the graphics have been revamped in every other way possible... And yet, there's still a damn good cartoonish look to it.
The music and sounds are great as well. They fit in so well I practically felt inside the game. While the funny yammering effects of the characters were nice, I'd like to see what would happen if they were replaced by some real voice acting. Maybe you tried it and it turned out badly. Heck, I wouldn't know.
The storyline, oddly enough, kept me intrigued and I really enjoyed it. The only thing I didn't like was how both James and Melanie stood up for Alex with little foreshadowing, although Samuel had plenty at the beginning. I just feel that for how bravely James and Melanie stood up for Alex, there should have been more scenes involving both of them, maybe at lunchtime. I guess these criticisms just show that I was really into the plotline, though, much moreso than the first or third of the series, although the first one was pretty funny.
I really enjoyed playing this, and hope you make more stealth games in the future. Maybe even a PSP Flash adaption! :)
