This is a very interesting game.
Here are my thoughts after trying to enhance all the color attributes:
- Of the effects of each color, the green poison is abnormally powerful in terms of annihilation (the other colors' effects, which only deal half or a quarter of the base bullet damage, are very weak).
- The satellite slowdown is too powerful, making the blue ice seem insignificant (a 10% reduction per enhancement might be sufficient).
- Since the cost increases after the first color, it's easier and stronger to simply enhance a single color, and there's almost no benefit or enjoyment in combining multiple colors.
I hope these points will be improved in the final version that will be sold on Steam.
