Thanks for playing, glad you liked it! :-)
There is a sfx when picking up powerups, just not health pickups. But yeah, some vfx and maybe a slight screen shake would have made it even better :-) When you pickup powerups though, it gets added to the active powerups UI below the vitals UI :-)
I wanted enemies to be able to get hit by asteroids, but was unsure if I should do it or not.
Tbh I was 100% on my own on this game, I didn't watch the Laser Defender section, I have actually barely watched the course :-D I only used kenney's assets due to the lack of skills in art, but I have years of C# programming experience though :-)
Thanks again for playing, and feedback :-)
