Oh, God, this game has an insane amount of particles, it's confusing ahah, but fancy. Anyway, the idea is cool, really reminds me of Time Rifters. Bonus squares are fun.
Yeah, the bullet identification needs to be instant, and it's not right now. Might need to slim down the particles / make the enemy bullets more apparent.
You know, there were a lot of games, that came out a while ago with very cool and original ideas. Sometimes those concepts and approaches became forgotten and rarely used. I understood that, when I met with Ultima IV about a year ago.
