I loved all the small paticle efects and the art was good even if it was simple. The movment was smoth and I realy enjoyed the dash. The one problem i had was that it felt a bit slow in the beginning but it realy picked up the speed round 4. Also one thing you need to do with this kind of power up system is to stop powerups from being negated by downgrades for example + damage but + enemy health. But its a good game overall, good job.
