A solid 3 star game.
Pluses: random drops, skills and upgrades to help you grow stronger and advance.
Smooth controls allowing for easy game play that is responsive and intuitive.
Creative back story.

Cons: fire rate seemed a bit slow.
Ammo options seemed mostly useless as only 1 did full damage, the others doing significantly less. The time from damage assessment to next shot was nil, making switching to finishing shots irrelevant. The added complexity would add to decision time with typically inferior results. It was rare to find conditions line up to make them viable as a better option.

Variation in drops relatively low, making for slow progress in upgrading equipment.
Shop provided 75% of the opportunities from each battle.
Multi-stat items are difficult to compare without buying and trying, possibly at a huge waste of funds.
No ability to drop down a level makes advancing to the boss levels risky.
Seems designed for phones:
- text hard to read on a PC
- annoying messages to download app to phone on the PC version that can't download them
- tall & narrow playing field when most PCs have a short & wide screen

Very addictive
just one thing: the long vertical screen without a fullscreen mode force me to play hiding the base and the shooter to see the first incoming enemies ... that's a pity
I would add some extra shooting drops by kills during the level :)
hope in a second chapter ;)

I can see this game becoming very addicting. movements are smooth and good animations overall makes for good gameplay.

It's progression is nor too fast nor too slow, it needs more soundtracks because the same one all the time, gets boring, Liked the "Random stats" so you play to aim for the better stuff.
I will think about downloading it on the Phone.

i played a bit (iam at work...) so for the first impression a nicely done top down shooter and the very nice thing is this super tutorial, really, also the technic-trees and stats. Cool game
