This is a fundamentally broken game.
It's impossible to really judge where you are spatially with respect to asteroids in the distance. There needs to be some kind of grid or forward shadow indicator.
Also, mouse is constantly moving out of the window and then doesn't interact with the ship anymore. That makes this virtually unplayable.
upgrade to "decrease hitbox size"
never seen that before. that's pretty cool.
i absolutely hate the skill system. i could not ever get a skill off without taking damage because i have to take my fingers off the movement keys to hit a number button.
why isn't it q/e to cycle active ability and right click to cast it? why wouldn't you do that..?
i changed them to space, shift, and ctrl, but how nice it would have been to have it on right click.
right click CAN be used reliably and consistently in web-based apps now, so you have NO EXCUSE.
still a good game but i don't like how difficult some of the stars are. like killing the first boss in less than a minute.
and despite upgrading my hitbox, it made no discernible difference whatsoever. oh and the weapon caps out at a really crappy damage level.
i consider it a cardinal sin in gaming when the player is forced to move their hand between the keyboard and the mouse.
No mention of the source of the sounds (Valve games, specifically Portal and Half life 2)
I don't like having to click twice to get to the next level and that the continue button is down in a corner while promotion links are dead center.
Another big flaw is that the name of the game is grayscale and that is a reference to nothing but the color scheme of the game. It in no way influences the game's mechanics. The name should have been to do with the actual mechanics at play.
Finally, I don't like games where there is a level selection screen and a clear boundary between levels with a score screen or something. It just makes games feel incredibly cheap. Much better to just transition smoothly from level to level without any reference to a level "number."
Lot of potential but some serious flaws.
but you can replay levels!
the electron is currently theorized to be a point particle. that means its radius is 0.
the milky way is significantly larger than the andromeda galaxy.
lots of inaccuracies here.
really good. really underrated.
might be nice to have a way to mitigate the minor frustration of the slow pacing of the bouncing. but i can't think of anything off the top of my head that doesn't significantly change the nature of the game, so i can't blame you for not having thought of one either. would probably have to be through level design.
