What could have been a very satisfying short experience, is sullied because of RNG.

QUICKERFLAK features high-speed combat with an extremely short window for reaction times that will result in either successfully moving to the encounter exit point, or death which will restart the whole run. While the enemy count/types is set for each encounter, the placement of said enemies and the arena layout is determined randomly.
While I understand the appeal of random arena layouts to expand out what would be a 5-60 minute experience, to be far more repayable. With the level of execution required to progress (and severe penalty for failure), without tuned layouts that can be learned, both achieving a flow state and death feel arbitrary.
(A compromise might be to have an option that sets the game to pause on each new encounter until the player presses M1. While I understand this would go against the intended frantic nature of the game. Without the ability to fully absorb information, it further exacerbates the feeling that wins/losses are almost entirely due to "good/bad arena RNG".)

If the dev made a more fleshed out spiritual successor with this exact visual aesthetic, sound design, and game feel, but with set levels. I could easily see it become a cult classic.
