Open-lvl Smups are actually one of my favorite game genres of all and you really did a great job with this one. It has some flaws(In my opinion the lvl are actually a bit too big, the shield goes down a bit too fast) but anyway, this IS an awesome shooter with a really interesting setting. I love to idea that you shoot stuff the cure, not to injure.
I’m definitely consider donating. Keep up the good work!
I like the idea of creating something, that´s not just fun to play, but in addition has a certain meaning.
Jesse Schell points out, that we as game designers should always be aware of our responsibility.
I mean, you could have packed your game into a running-amok-setting - with exaclty the same mechanics. Replacing the level with a school, your pod with a armed kid and the “enemies” with teachers and students, running around. Apart from the fact, that this would be absolutely tasteless, you would have had a lot of people talking about you (and your game) in very short time. The last point is mostly seen as a plus.
Like I said, I really like your approach, but I would change the mechanics a bit. The biggest problem in cancer fighting isn´t to kill the cancer, but to kill the cancer, while the patient survives. I like the idea, that the patient is the level, but what if the patient has a health bar?
You are starting with your pod, the enemy is starting with a few cells, in a level full of healthy cells. The enemy (cancer cells) are able to infect other, healthy cells, so that cancer spreads through the level. You are able to kill these cells. Not just the infected ones, but also the healthy ones. The more healthy cells survive, the higher your score. If the number of healthy cells drop under a certain point, the patient - and also the game is lost. In addition you can also introduce some lethal points (organs), that have to be defended by the player.
