Hello and thank you for your comment! We really appreciate how constructive your review is, It really helps us improve the game
Our team is currently working on the second level for Chroman, it should be available later this week. New enemies, mechanics and a player color will be introduced in this level.
We have also felt that the dash gets forgotten quite easy after the first lasers, and is not often used by players while fighting, that's why on later updates we plan on creating new enemies that involve more use of this mechanic
Also, our team has discussed how we can implement secondary attacks to each of the player colors similar to what your suggestion is, but unfortunately this won't be available until later updates.
