  • shop panel before each level : a menu to spend money on spacecraft upgrade (see above feature)


Development :

Astral Crusade started in mid january 2024. It's a one man project written in C with GBDK. The idea behind Astral Crusade is to build a side scrolling SHMUP with a bit of rogue lite feel. Before each level the player can spend hard earn credits to boost his spacecraft. The goal is to offer game style choices : would you play a quick hightech and fragile spacecraft or rather a slow, powerfull and resistant spacecraft. This is only one exemple.

AI was used during game development, specificaly in artwork. More on that in an upcoming devlog.


Roadmap :

  • during 2024 : web demo will be published here.
  • end of 2024 : full playable game.
  • 2025 : physical release
