Due to a very low interest in the game, I decided to postpone the development and continue working on my other projects until gamers get more interested and engaged, leaving comments or contacting me.
Everyone who I personally know were interested, but the interest over the Internet is currently quite the opposite. There's still 4-5 months, maybe even more, of work left for me to do to finish the game fully, the way I intend it to be, and it's quite a lot of time and effort for something that only a few dozen people will play.
I thought, since it's a game more closer to classic shmups, with a several interesting original features and mechanics never seen before, the interest would surely be bigger than interest in Invader Attack 2, but the case is shockingly opposite. I still don't get it why, but since there's not much feedback coming from different gamers on the Internet, that part might remain a mystery to me.
The game doesn't have a main menu currently and there are only 3-4 levels, not fully finished though, but it is playable, so if anyone is interested in trying this prototype (still alpha version prone to larger changes), let me know. I'd also appreciate any feedback based on just teaser of the game, is it something you'd play or not and, if so, why not. These things do help and shape the development.
