Nice idea but there are far too many eggs on the screen! It is impossible to evade them. Also "play again" should redirect into the game instead of going to the start screen.

Could be Gunforce 2 aka Geostorm. It's from the 90s and starts on a train.

DavidA13 Of course I saw them. But like I said: They don't explain everything. Let's say i pick up a 3 and add it to a 5. I get an 8 but on the free space I took the mentioned 3 from a new number occurs. Sometimes it is a 1 a 2 a 3 or something else. By what rules are these numbers chosen? I would put the answer to that question additional into the tutorial bubbles.

Was in search for decent pixel animation software. So I decided to give it a try and bought the humble bundle. Scrolled through the manual. The software looks like what I was searching for. Thank you for the link!

I liked the music and the overall dark atmosphere. But the game is far to slow paced. Also there seems to be some graphic issue: The whole screen is very bright as seen through frosted glass. I'd also use smaller sprites. So the player would have a better overview on what is going on.

The irem classic Image Fight is my alltime favorite in this genre. It starts out simple but has a steep learning curve. They put some thought in the enemy spawning points and as well as in the enemy behaviour. Level design is decent and the boss fights are pretty clever. The last levels are really, really hard but fair. Also the way you pick up weapons, how they work and how they are arranged around your ship as shields is made very good. You can purchase it from dotemu.com with the irem arcade hits collection but I can't recommend this bundle since they messed up the sound.

Check out this youtube playthrough:

Use asset stores.

Use Gimp and Krita. They are both free to use.

eliasfrost Thats good since from what I see this game will be a hit!

By the way: I'm unable to see the gif you loaded up on Wed Jul 15, 2015 9:18 pm. Tried firefox and opera. Seems to be something wrong with it.

eliasfrost Are you going to release it commercially?

DavidA13 I've played it on your site and I have to say: It is indeed addictive! My highscore was 585. I found it very clever. But I would definitely put a optional tutorial or a how-to-play into the game. In the beginning it is hard to tell by what rules the new tiles are added.

eliasfrost Somehow I managed to miss Blackthorne... Thank you for the recommendation. I will look into it.

Do you already have a story idea for "Razzia"?
