This is a VERY well made twin-stick, arcade-based SHMUP. 3 lives to start with (you can earn more in each game as you progress through each screen), a gun that you can upgrade (destroying certain capsule-like objects will give you a specific weapon upgrade - static [the first one you find will always give you a double shot, second one will always give you a triple shot, ect...], and they're always found in the same spots), and you're off!!
You destroy enemies and certain objects+hazards (spikes, barrels, rockets) while avoiding enemy projectiles and lasers, making your way from room to room in a huge, interconnected facility, trying to get the highest score you can before you die.
If you loose a life, you're sent back to the beginning of the room you died in and your weapon reverts back to its beginning, one shot, strength.
The only negative thing I can say about the game is that the static joysticks are fairly small and when your fingers drift outside of the circles, they stop responding. This doesn't happen with the floating joysticks, but I prefer static, so this is kind of an issue for me. Other than that.... this game is near perfect.
.... well.... it would be nice if high scores were tracked with GameCenter instead of just going up against 'developer scores' like most 80's arcade games (10th place is 100,000, 9th is 200,000, ect... [these aren't the actual scores, just an example to give up an idea...]), so if you're super big on GameCenter scores and knowing where you place worldwide among other players, you'll be kind of disappointed.
But... if that isn't a big deal for you, and you prefer floating joysticks (or use a physical controller), this is an AWESOME arcade SHMUP/score chaser that's heavily influenced by 80's and early 90's coin devourers.
The difficulty is perfect (hard at first, but the layout never changes, so you'll be able to memorize enemies, patters, behaviors, ect, and get further with each try (usually).
There's 2 game modes.... a wave based endless mode and the main 'campaign' mode where everything is set in stone and you can have a real feeling of progression as you learn and dive deeper into this facility that's filled with MANY things that want you dead.
It's a steal at $2, and I couldn't recommend it more for fans of the genre.
If you're not into fairly hardcore arcade games, this might just frustrate the bejesus outta ya, but.... some people are looking for that too.... so.... have at it!
=D
To the devs:;: I hope more flexibility can be added to the controls in a future update.... other than that - FANTASTIC job with this!! Can't wait to see what you potentially come up with in the future!!
=D
