About this game

All aboard the Cosmic Express, a delightfully brain-melting game where the puzzles are out of this world! Your job is to lay down the train tracks across a series of tiny space stations. Each alien has a home of their own, and there’s only room for one extraterrestrial at a time in the passenger car. It's cute, harder than it looks, and guaranteed to give you hours of challenging fun across hundreds of levels.

- Fiendishly difficult puzzle design from master puzzle creator Alan Hazelden (A Monster’s Expedition, Sokobond)
- Ultra-adorable graphics created by Tyu Orphinae (Klondike Collective)
- Relaxing ambient soundtrack by Nick Dymond (Maia, The Colonists)

I can't believe I had to look up the walkthrough for level 2! xD The game didn't really explain much on level 1. After a few levels I saw how fun and puzzling this is, surely a game to get lost in for awhile with cute sounds and nice graphics. Unfortunately for me, I don't think this is a game I can get into at the moment, as I'm trying out a bunch to see what really grabs me. Maybe one day I'll try again. I'm giving it 5 stars for the concept, art, and challenge. :)

A brilliant, fantastically challenging puzzle game for veteran puzzle gamers. The level designers are freaking genius masterminds that never fail to stump you. These puzzles get really difficult while always looking simple on the surface, sorta like Snakebird. You know a puzzle game is great when you conclude that a level seems logically impossible, and then days later you decide to give it another shot, and a short time later you manage to solve it. This has happened to me multiple times now.

First off, let me say the actual concept and puzzles are excellent, 10/10. However, I can't understand why the play button is in the bottom middle of the screen. Makes it very frustrating trying to edit track when it's under the button. Why not put it in a corner like the other 2 buttons? Another thing is the game doesn't work well with higher resolution. My s10+ has a ~2k display, but I don't think this game even runs at 1080p. Looks noticibly pixelated.
