I just noticed the timer that pops up after beating the boss. I think it could use a box or something around it rather than just an empty mask. Also, the smooth walls feature makes a big difference, in my opinion.

Hmm yes good idea, I'll look at implementing something like that to make the timer stand out more

Wow, that looks really cool, i like it! I always thought that the screen was small enough without limiting the range of view even more, i think the new darkness looks better and will be a bit less frustrating

It stands out much better with the border, i didn't even notice it before the first few times i saw the screenshot. Btw, while it's a small detail, what would you think of removing the corner pixels from the box to make it look less.. square?

Yeah, i think your version looks even prettier

TBO I prefer the previous version

Wow, tons of changes. I wish you'd released this a week earlier as i've had several long bus rides the past couple weeks. Anyway, congrats on the release!

Thanks man! Took me long enough..

I just downloaded Alien Breed and I really like it! I just wish it saved instead of using passwords.

I have a "quick-save & exit" type feature on my to-do list for the next minor update, which I expect I'll get around to doing in the next couple of months. However I don't plan on having multiple save slots (like RPG type games).
