I created this game for NexZen Studios GDevelop jam, using the GDevelop engine, obviously.
I made it within the time of the jam, but ran out of time to add sounds and explosions, and any polish, and it didn't get a lot of play-testing either. I did try to make it playable by those who have trouble with colours, so if you have any feedback on how well I did, I'd appreciate it.
Let me know what you think if you do try it.
This is all my own work, except the idea, which is from the creators of Space Invaders. You youngsters might need to google it.
