Synopsis

A side-scrolling action platformer, crowdfunded as a spiritual successor to Mega Man, in which the robot Beck stops a wave of rogue machines. You shoot enemies to weaken them, then dash through them to absorb their energy for speed, power and score. Each defeated boss robot lends Beck a new weapon to use in later stages.

What people say

Critics and backers were largely disappointed at release, faulting dull level design, flat visuals and voice acting, and a result far from what the crowdfunding campaign promised. Steam reviews remain harsh, centering on an underused dash mechanic, instant-death traps and repetitive boss fights. A minority of players enjoy its fast pace and flexible weapons and suggest buying it cheaply on sale. It is now mostly remembered as a cautionary tale about crowdfunded games.

2.5 / 5

✗Controls feel awkward on a modern controller or mouse and keyboard
Reviewers call the dash imprecise and say spamming it, even in midair, trivializes platforming, and DirectInput pads can have broken sticks and D-pad until calibrated. Source: pcgamingwiki.com.
✓Menus, text and interface are clear on today's screens
The game supports 4K and full XInput controller play with remappable buttons, and its few menus are plain and readable, though the borderless window mode does not work. Source: pcgamingwiki.com.
✗Saving is harsh: few saves or checkpoints, progress gets lost
Losing all lives sends you back to the start of the stage, and collected energy tanks are lost on death. Source: pcgamingwiki.com.
✗Hard to make progress without a guide
The tutorial leaves out several moves, and many deaths come from instant-death traps hidden past blind jumps. Source: pcgamingwiki.com.
✓Pacing holds up: little grind, filler or forced backtracking
The game is short and linear with no grind or backtracking, although stages are often described as bland. Source: pcgamingwiki.com.
✗Camera or movement fights the player
Several reviewers complain of blind jumps onto hazards that cannot be seen in time. Source: pcgamingwiki.com.
