ABCDEFGHIJKLMNOPQRSTUVWXYZ

encodes to

QDFOZNMLTKJIACSRBXPWUEYGVH (basic substitution cipher)

and that a recipient called the ohce can undo echo

liked it very much

for some reason people hate on solving simple equations in a puzzle game, but I actually enjoyed it

the rules were pretty simple and well telegraphed

very fun game, but I would say that some of the puzzles in green were a bit too algebric, 2 of them made me to use algebric equations. Not sure if it was intended

Very fun. I highly recommend puzzle lovers give this game a shot. Some of the puzzles are really difficult but finding the right spot to start makes all the difference. Good luck and remember to follow The Path.

i think i wouldve enjoyed it more if the ways to proceed to the next part were less telegraphed. (for instance not bolding keywords in documents or giving the order for the anag.)

Absolutely engrossing. A friend sent me the link to the online version, and I couldn't help but play it wholly. Love how it blends and improves on KenKen, Sudoku, Flow, and crosswords (and no doubt other influences and new ideas). The rules are abstractly but still clearly explained, and the puzzles are nicely challenging. It's getting late now, but I'm going to replay this tomorrow just to see if there's any secrets I missed.

P.S. Is the "C P V V B D G" IVRI FDI ZMYLFX OSMNVO QVITVVF VMNZ 'C P V V B D G' intentional?

Was fun until the game became solving systems of equations. Everything apart from the last area was fun otherwise.

i will also join the Icely bandwagon, stopped the video immediately and enjoyed the game all by myself. what can i say... stellar puzzle design. i really had an epiphany playing this and THAT's what a good metroidbrainia is all about. Bravo to Sufferbox!

also in the Icely camp, played it instead of watching their video. phenomenal puzzle design. i did skip BLUE-8 by checking their video for the solution because i did NOT wanna figure that out lol. me problem, not the puzzle itself i assume

very delightful! found this via icely's playthrough and it intrigued me so much i stopped watching and decided to actually play through it myself. very fair and logical puzzles throughout.

Excellent game, had a lot of fun with it.

Very cool game

This is one of the best puzzle games I have played. It rivals the likes of the witness for me... I look forward to seeing where the dev(s) go from here :)

I really appreciate the hints in the help desk. It's always hard to balance being helpful without revealing too much, and the ones I used in this "game" worked perfect for me.

I had a great time playing "The Perimeter" thank you for sharing it on Metroidbrania subreddit <3

The puzzles were quite fun! I beat it in about 2 hours, and only had trouble because I didn't realize that blue's path could go straight through a tile.

Here's a tip for anybody that's stuck on a level: write down all the sums, then try to solve one variable at a time.

The PERIMETER must not exist.
