I have 3 Steam keys for Tricone Lab, a puzzle game the kind I enjoy: no reverse-engineering of the author's brain, and oftentimes multiple approaches and solutions.
The game is a bit on the easy side, although it was perfectly suited for an appropriate teasing of the grey cells here. A very handy level editor is built-in.
Which leads to this: it is early access as, as far as I understand it, the author has been trying to get more levels done for a proper release. The game itself is finished.
I actually tried to build myself a collection of a few levels, under the name PhilosOffer, accessible to download from within the game, if you care to give them a try.
PM me, if you are interested. I'll hand the keys tomorrow, and in the -improbable- odd that so many people message me I can't hand everyone a key, I'll do an amazing drawing like those Youtubing superstars.
