Very good! Finished the game, then finished it again.
A lot of fun in simple mechanics!
Please fix the spontaneous jumping bug.
>What happens when you reach the pink thing on the right ?
You win the game.
>Please add some short instructions.
Understanding what to do makes games less FUN. Explore. Try. Fail. Fail again. Give up. Give up harder. They are closer than you think.
>Music in relation to the enemies (number/type) on screen would be fun.
Enjoy the silence of space.
This game is about RAGE and you must FEEL it. I want you to HATE vampires, and try to kill them in groups with as few noise as possible and without missing any shot. So the sounds perfectly match the design idea, as well as hardcore random: you may win in 3 minutes or spend hours without getting a single victory point.
I didn't understand anything on the first try. What do I control? What's happening on the screen? On the one hand, a small tutorial would be nice, on the other hand, the mystery gives the game a certain charm.
On the third try I realized which square I was controlling.
Around the sixth - what needs to be done.
It took about two dozen attempts to get a feel for the timing. It would be faster with a countdown sound, but it might not be more fun. Have you experimented with this?
And no matter how much you study, sooner or later you will get distracted and make a mistake. The game requires really strong concentration, a sense of time, and a habit of speed.
On the first try, you think this is impossible.
By the fifth attempt, you understand the principle.
By the twelfth, you already "feel" the map and just try to press the buttons quickly enough.
This game could be an example of a really good learning curve, impressive design, I like that kind of thing.
I could implement most of this, but then there would simply be NO WHERE to play it all, so I started with level design (avoiding the mistake of the previous jam, where I did not have enough time to create playable levels). Sooner or later I will find a good balance =)
