Saw your post on Twitter and came to check the game out.
Whuf, I am apparently terrible at this game since other posters are mentioning scores of up around 500. But it was fun! I liked the short gameplay style, the quick action, and being able to play in the browser. The combination of direction and color made for a good challenge.
Some suggestions:
- Alternate keyboard controls, such as a configuration that lets you use the arrow keys to control facing might help some players less accustomed to WASD controls.
- The pixel art characters were pretty charming! Love that little frog person. I'd love to see a nice background to go with them in the same style.
- Red/blue color blindness might make this game hard to play for some people. You might consider having a way to quickly differentiate the monsters other than only color. (Would also be a way to get more of the aforementioned charming characters into the game!)
- Maybe "bosses" who take two or more hits to defeat, but get knocked back a bit when they receive a hit or approach more slowly?
Anyway, a fun, quick game. I hope you keep working on it to develop it further.
