I thought about tying the dash to the mouse, but it made it really awkward to activate abilities, and I kept dashing away from the core. Honestly, that was super frustrating!
Besides, by the mid-run, the dash usually gets swapped out for extra damage or defense anyway.
As for the timer going to -6 seconds—the thing is, when the timer hits 0, enemies stop spawning. After that, you just have to finish off any remaining enemies, and then the victory is counted. I probably should have disabled the timer at that point, but I totally forgot about this bug, hahahahaha.
Thank you for such a warm and thoughtful feedback! Thanks for playing my game, and thanks for the text emoji at the end—it really means a lot to me! :3
