Good effort and glad you could join us in the jam 💪.
Gameplay
It is a short game. The idea is nice to be able to eliminate waves of enemies. It's a pity that making several waves didn't work out in the end. The reloading and shooting might need some polishing in my opinion. It was hard to see where you shot except through the crosshair. Maybe also show the bullets flying or a laser beam. Also when I had to reload it would be nice to get a notification in the HUD or something like that. Spreading of the enemies would make it more a challenge.
Graphics
3D is nice and the weapon looked good. Some more obstacles and variety in the environment in an update would be nice. Skybox was good.
Audio
Unfortunate there was no sound. Audio always gives games that extra polish. Try to add some in your next Jam or update of this game. It will help build an ambiance.
Theme
Space shooter on mars...check 🙂
Devlog
None found. Would have liked to read how you made the game and what problems you had to solve. Hopefully you can make one next time.
Well done and keep up te good work for future games!
PS: an icon for .exe gives your game a more unique look 😉
