It looks pretty cool ! The melee attack feels great, dashing through a group of enemy is really fun ! However it feels like there is no real challenge, enemies are very predictable and slow, and with the dash they look more like a way to travel faster than dangerous things. Maybe they just need to fire projectiles, to force you to be careful on your positionning ?
I also had the crash after a few minutes so I don't know if the difficulty ramps up over time or not.
