Hello, I tested your game and I'd like to answer your questions in the comment below :)

- I found the game enjoyable and fun to play, and I don't think the game in itself is difficult, it's just not easy to kill ten enemies. The fact that they're constantly shooting at me make me flee all the time, trying to kill some of them who where a little alone before the others came. So I didn't really felt in a game where I have to shoot my enemies, but rather in a survival game. Their regeneration and strong use of their shield didn't help ^^"

I found the concept of attacking and defending very interesting, you should develop that further. Maybe in a new version i'd like to see some bonuses (like gaining more ammo, regenerating too, different kind of missiles and shield, speed, etc...), maybe having the cam less close to the ship, which currently take too much space screen. And if the purpose of this game is actually to sweat blood and water by killing one enemy, maybe having a little reward ^^. Oh and showing more clarly our goal, by adding the requested number on the counter (1/10, 2/10...).

I say all this but it's absolutely not negative, I understand you made this demo during a game Jam and you did a great job :)

Sorry for the bad english and thank you,


Oh your game is cool, more fun than I expected. Would be curious to see how you would develop this further?

Thank you for your kind comments. I hope you don't mind if we ask a few questions.

Some people have said it's very difficult.

- What was your experience?

We do intend to develop this a bit further. (Jam games rarely meet the initial design goals :)

- What features would you like/hope to see in a new version?

It felt very easy, since as soon as you stick to a trick you cannot lose. Maybe they didn't use move keys. I would try to prototype how it feels if the block (defense) also was shooting bullets, instead of getting stuck at the edge of the cell. Then you could put stuff inside the cells, that you need to protect (like boosters) and add more enemy types with different behaviours.
