Who Makes Island Evolution
One developer, one rule table, and every number on this site checked against it.
Island Evolution is made by one independent developer, who goes by Leshrac. There is no studio behind it, no publisher, and no team of writers. The game, the evolution chart and every article in the blog all come from the same place.
What I actually built
The game runs on Godot 4 and is exported to WebAssembly, so it plays in a browser tab with no plugin and no download. The rules are not written as code branches. Every item, every level and every growth condition lives in a data file, which is what made the next part possible.
I ran all 40,320 possible orders through those rules and recorded the outcome of each one. That is where the numbers you see repeated across this site come from: eight items, 40,320 orders, a maximum score of 27, and exactly three orders that reach it. They are not estimates and they are not copied from anywhere. They came out of the game's own rule table.
The art is original pixel work, drawn at a 426 × 328 canvas in Aseprite and animated in engine. The evolution chart on the front page is generated from the same data file the game runs on, so it cannot drift out of sync with what actually happens when you play.
Where the orders are
The three perfect orders for this game are on the order solver. They came out of the same rule table as the 40,320-run check, so they can be derived and they can be checked. The page also lets you test any other order.
Click orders for GROW Cube, GROW Island, GROW RPG, GROW Tower, and GROW Valley are on those articles. Each one is a sequence that at least two walkthroughs list the same way, and the pages link those write-ups. I do not print an order when the sources disagree. The strategy guide is that method, and the hints are the short version for this game.
How I handle facts about other games
Several articles here cover the GROW series by On Nakayama at Eyezmaze. I am not affiliated with them in any way. Release dates, item counts and platform histories are checked against published records before they go in, and where I could not verify a date I leave it out rather than guess. If you find something wrong, tell me and I will fix it and say that I did.
How the site pays for itself
Advertising, and nothing else. There is no account, no newsletter, no paid tier and no data sold. If you decline cookies, no advertising script loads at all. The details are in the privacy policy.
