Looking at the itch listing I didn't expect much. This brings a classic game into 2025. You have variety in enemies. Tuning that lets me play as long as a like.
No clear objective, other than score and survive, pure jam goodness.
The power up system was confusing. Kept choosing wider shots and I got some small text in the right hand, that didn't seem too responsive to my decisions. Over time all the right panel was saying ++ projectiles, or words to that effect. Not sure it made much difference, but it was a nod to the theme.
