Ayy thank you for playing for our game! (Your game was quite polished as well btw!!)
You can go through enemies while you're dashing (there's a brief invincibility time during dashes so you can outrun enemies/go through them if you're cornered)
As for staggered/stunned enemies (which you'll need to unlock through upgrades), I may have forgotten to code enemies to stop attacking while they're staggered (Oops... XD), they just stop moving & I think the hitbox still automatically damages the player. Will defo address this in a future patch sometime after the jam, Cheers! ;)
