The graphics do look nice, so your time spent was worth it. I can the influence from the Galaga arcade game. The gameplay was decent, and I mastered the controls quickly. If you added a way to purchase upgrades, it would be an improvement.
Reviews for "Zyrlimoon"
Simple and not bad, had some odd handling though, but I think it was on purpose. Overall it wasn't the most original thing, but it had some good graphics and fairly balanced game play for this type of game in 2002.
Great shmup made far too difficult due to enemy bullets that are far too hard to see. The game looks and plays really nice though.
