Note: If anyone else is new to java, make sure your java is up to date, and open the jar file with javaw.exe (worked for me in windows)
What I liked:
Pretty cool game, and I can tell you put in hard work.
Neat sound effects, very nostalgic for me
Cool graphics as well -> nostalgia factor
Suggestions:
A OST could make the game more memorable.
Moving off screen makes you appear on the other side (like in pac man) -> If memory serves me right, space arcade shooters normally don't have this happen
It was VERY challenging -> I could barely get past 1 enemy.
A start screen would be nice -> Though I'm a hypocrite here since my own game didn't have one.
Overall Impression:
I liked it, and this was one of my ideas when I was brainstorming. Fun little game!
P.S.
I'm also learning java, how did you implement the high score function into your game?
