Cool game, reminds me of a little of vampire survivor and Mindstorm on Vectrex ( from 1982)!
Wasn't sure if this was a bug but if I didn't pick up the health item and it despawns, it doesn't respawn again. Perhaps maybe I just had bad RNG!
Thank you for playing it. I had to look up both games you mentioned to understand what you meant, but there are definitely similarities to both, I agree. Minestorm for Vectrex seemed a lot like Asteroid for Atari (one of the first video games I ever played).
I do not think you were experiencing a bug, just an oversight on my part. The chance of a pickup spawning was 1 out of 9 with an equal chance either for the special ability pickup or the health pickup (cutting that chance in half gave you a 1 out of 18 chance for a health pickup to spawn).
After playing the game for too long, I had decided it was too easy and had decreased the chance of pickups spawning. I should have played it longer with the new RNG to make sure the increased difficulty still made it fun.
What would you suggest? Maybe double the chance of a pickup and extend the despawn time? Thank you again for playing it and providing feedback.
I see! I assumed the rate was much higher since I was lucky enough to frequently get them in the beginning. IMO the current rates seem fine but you could go with what you suggested. In addition, you could also try having the spawn rates slowly fall off overtime for added difficulty. Might spice things up abit.
Cheers!
