Agree on the crosshair feedback below, something like a hexagonal outline would look appropriately sci-fi while not obscuring vision. Nice fullscreen dither and feeling of being in the cockpit, I'm a sucker for that stuff :)
I found that it was sometimes hard to tell if the Dash was doing much - maybe it needs to be more intense? Maybe an anime-ish screen effect?
Other than that I enjoyed circle-strafe-cheesing the enemies a la Doom. Makes me think that with more time, this could be the pace & feel of classic Doom mixed with the customisation, heat/energy management etc... of PS1/2-era Armored Core. Homing enemy projectiles that require Dashing at the last second might be cool too. I like it :)
