After the next store update on July 14/15 the much mistreated Playstation Mobile store will be gone, an article in case you missed it, and while a couple of game got a native Vita upgrade a lot of games will be inaccessible.
Let's go for a last round of recommendations since there are good games.in there, I'll start with a few of my favorites
Passing Time
From the developer of Frobisher says and Hohokum, this is probably one of the best short burst" games ever. It's a football game with a simple premise tap any player to pass the ball around, you can play a full match or different challenges and hings can get pretty intense.
I always go back to play for a few minutes, super fun and well made and is well worth the $2.79
Saicoro-puzzle*KURA:ssic
Puzzle game a la Puyo Puyo, you get a piece with two numbers from 1 to 6 that you can rotate, once you match three consecutive numbers in any direction you clear the pieces like matching 3-4-5 or 6-1-2.
The stages have a score goal and the only way to clear after the first couple of stages is to create combos, simple premise but it works great.
The presentation is very nice and you can even win wallpapers for your Vita! the game is free to try and you just buy the unlock key for all the stages and an endless mode for $1.49 I believe, just give it a try trust me.
Chiebura
Arcade shooter, you have a grappling hook and you need to hold the button to grab onto the same place and doing that you can also shoot in any direction but the screen auto scrolls and you have enemies and.projectiles coming from all directions so you really need to be swinging all the time and it can get pretty frantic.
Super fun and it controls great, AND is just one dollar! just go and purchase it
Magic Planet Snack Deluxe
You control a worm and try to collect while avoiding enemies, once you collect enough to hyper letters on the bottom so you can turn all items and enemies into snacks for more points.
It's a fun score attack game that gives you that "one more round" itch as you play, it's only 0.79, oh and you can play it vwetically in hot dog mode.
Other stuff
PSN stores archived stream of over 5 hours of PSM games, it's a fun watch and the games played with their time stamps are in the description
Instructions on how to keep the games after the shutdown
I'll post more recommendations, but do share yours, ask for suggestions and of course go get some games before they are gone!
