Alien Diver is a very untraditional IF game, which combines some standard IF conventions with a card/dice game. Thus many things are randomized and thus different each time you play.
The backstory is fairly simple: On a scouting mission you crash-land on an ocean planet. Even though your spaceship can travel underwater, it must first be repaired. Before you can do that you must first find your ship, which you floated away from while you were unconscious. You must also collect four coloured fragments before you can repair your ship.
You must do all this within some time limits. Your ship is slowly being destroyed by the ocean if you don't repair it soon, and you may run out of oxygen soon too. There are ways to get more oxygen, but to my knowledge, there is nothing to prevent the ship from being destroyed, unless you manage to repair it.
So the gameplay consists of you racing around the ocean, trying to find your ship and trying to obtain these coloured fragments, while avoiding deadly sea creatures.
The coloured fragments can be obtained from the many alien cubes scattered around the ocean. A cube can only be used once. You can "roll dice" to try to and match the power number of a cube. If you fail you get a single crafting fragment (different from the coloured fragments). If you succeed you get three crafting fragments and you can then extract a blank card from the cube. The cube is then inactive and cannot be used again. Whenever you extract a blank card, the extracted blank card has a sea creature symbol. If you encounter a sea creature you can play this card to help you, though you can also attack it in a more traditional way.
But you might want to save your blank cards for something more important. If you find an active cube and you have a blank card, you can craft a card. The crafted card will then have the same power number as the cube you crafted it on. Again the cube becomes inactive.
You can then play a crafted card next time you find an active cube, though the power number of the card must match the power number of the active cube. If it does, you obtain a coloured fragment with the same colour as the cube. You must collect four different coloured fragments before you can repair your ship.
The built-in map feature of ADRIFT 5 is crucial for this game, since the map would be a pain to map because of the many curved connections. Thus it is highly recommended to download the game if you have a Windows computer (the map of the online runner is not very flexible and on Android you cannot display the map). However, the map is not randomized, so it should be possible to map it if you want to.
It is hard to explain but this game is a lot of fun. The difficulty level is not high, but you may need to restart a few times until you have settled on a good strategy.
If you don't mind strategy elements in IF games, I can highly recommed this one.
If you ever saw the movie Big from 1988, you might remember that the main character was playing an IF game with graphics. This wasn't a real game, just one location made for the movie. Then in 2009, BoMToons created a game with only that location.
Then, in 2020, MontieMongoose created this game, with several locations and original puzzles and the final location is that, which is shown in the movie.
The graphics style matches that of the original movie, which is fine. However, the movie was published in 1988 and there were many games with decent parsers at that time. It couldn't be seen in the movie if the parser was good or bad.
This game has a homebrew parser and the parser is very bad. Still, the game is fun, since you are told to use verbs like GET, THROW, OPEN, EAT, USE. Most of the game you use these verbs, except you also need LOOK (EXAMINE is not understood) and NORTH, SOUTH, EAST and WEST and in the final scene, you need to use a series of commands which I believe no one could guess without seeing the movie (there are videos on Youtube showing how to beat the final scene).
Thus I would recommend the author to implement the game in an IF-engine so the game would have a much better parser. Especially the end scene should accept more commands than it currently does. I am sure that the game would then be more fun to play.
Still I had fun playing it.
This game is not a typical piece of IF. You are sitting by your computer, checking your e-mails, contacting a few contacts, decoding secret messages and controlling drones. The game takes place in the year 2120. I won't reveal the story since it is slowly revealed why you play. The game takes place over several days. Each day you stay at the computer until all the things on your checklist have been fixed. Then you log out and come back the following day.
All the text is displayed within a picture containing a computer screen and a few other things including a window. Each day there is light coming through the window until it gets late, then it gets dark and you may see something moving outside. All this adds to a cool atmosphere.
If you don't know which commands you can use, type HELP. Once you get the hang of the game, it is pretty straightforward so you probably won't get stuck at all.
I enjoyed this a lot and highly recommend it.
