starts off with your character (I guess his name is Gomo?) waking up to find his pet is missing. After a very brief search, you are sent a video from some kind of space creature. It appears that he has stolen your pet and demands that you go steal some kind of gem and exchange it for your dog. Quite frankly, it feels like a very shaky setup and only an excuse to have your character go through a series of underground chambers in a nearby mine and eventually into space.
What follows is exactly that. Each screen poses some kind of logic or inventory puzzle for you to get past in order to go to the next scene. For the most part, you enter each screen with no inventory items, and you leave using up all of the ones you picked up in that area. There is a kind of simple charm to this design and for the most part, it works. Unfortunately, the side effect is that everything you need to solve your problem is on that screen and the result is fairly straightforward and simple puzzles.
Given this design, it seems like there is one major benefit to the game. Namely, you don't really have to remember what you were doing and what tasks you were trying to complete if you happen to leave the game and come back to it after some time. After all, the only thing you need to do is get past the puzzle in front of you and move on to the next. An interesting side effect to this is the fact that you don't ever save your game. Instead, it looks like Gomo saves every time you change screens.
This actually caused a problem for me at one point though. Early in the game, there is a puzzle that actually requires you to go to a different screen in order to get all the info you need. This rare event in Gomo meant that I could leave the screen having only picked up some of the inventory items I needed, and returned still needing to get some things. Well, in this particular case, I picked up an item after coming back into a screen and ended up having to stop playing for a while. I closed Gomo and returned some time later. When the game launched again, I found that I only had some of the inventory items I needed and the last one I had picked up was not in my list of items. No problem right? I can just grab it again right? Nope, the location of the item was not clickable and I actually had to start the game over in order to get past that particular puzzle. Pretty annoying, especially given the unskippable cutscenes and random animations that the game essentially stops all progress in order for you to watch. I'm just glad this event only happened once and it wasn't too far into the game.
Gomo also offers three bonus stages you can unlock if you just happen to notice and pick up three random pieces of garbage in the world. Of course, you don't know that this is an option or that you should be looking for them, and quite frankly, I had to go to the Internet in order to learn this particular tidbit. If you are playing through Gomo and you happen to not unlock these stages, don't worry too much. All you are missing is three whack-a-mole games with different backdrops.
