Seems just like Resogun.
Yeah.. Kinda had a similar feeling midway through the development until the addition of the hero character jumping out of the ship, switching to different ships and various additional support pickups were added.
Work is still on for a few more levels, bosses, weapons & game modes. Also spending quite a bit of time to polish the visuals and interface designs. Will factor in your feedback. Hopefully at the end of it all, its able to deliver a gameplay experience like none other. :)
In mean time, please do share in case you have any other feedback or suggestions. Thanks.
