No-frills arcade shooter 

There are two ways to play BrightGunner, with the first being the Standard Mode, wherein you'll battle enemy waves across multiple levels with unique layouts and environments, including a river, mountainside, and a castle made of glass. The other is Survival Mode, which will test your skills and how long you can last against an endless onslaught of enemies. 

In addition, there are six special modes that offer different types of gameplay experiences, such as the Sniper Battle, Boss Battle, and even a dedicated Story Mode. There are also roguelike elements to the experience in that monsters and items will appear at random. The sense of unpredictability contributes to a steep difficulty curve in some levels and scenarios.

There are even multiple modes to choose from depending on the type of experience you want. It will be quite challenging for some but if you're up for it, check this one out.
