Astro Combat

Features:
[Skill System] - You can select Skills in different Skill Trees. The more you invest into a Skill Tree, you unlock stronger Skills. Each Skill has Skill Modifiers, which can modify what the skill does. Once you invest into a Skill Tree, you can still invest into other Skill Trees, which allows you to mix skills and have a unique build.

[Item System] - Similar to other Action-RPGs, Astro Combat has an Equipment and Inventory system. There is also a Crafting System where you'll be able to create equipment from material you earn from defeating enemies.

[Mission System] - You'll be able to select from 5 missions. Each mission has its own difficulty, in terms of mission modifiers, enemy type, bosses, bonuses, etc. Once you complete a mission, a new mission generates in its place. There is also a sort of "Mission Shop" which allows you to customize missions by removing, adding, randomizing features on missions.

[Combat System] - Once you've selected a Mission, you'll be place into combat. Before Combat begins you have time to set your Skills onto the Skill Bar, and sort other things out. Once ready, you'd press the "Combat Begin" button to start combat. Enemies will begin appearing from the right side of the screen moving towards the left. Use your Skill Keys and Basic Attack to destroy the enemies and earn EXP and Scraps.
