I'm sorry, but your fun is in another castle
Let me just get started. I did not have fun with this game, even after beating it. He are a few of the reasons why:
-Infinite Upgrades makes advancing to higher weapons next to pointless
-Enemies can come at such a overpowering rate that you can't kill them all
-You also can't dodge shots once you get more powerful weapons because your castle ends up being too large, which makes the new weapons even more pointless
-Rapid fire is slow. I mean slow. I don't know about anyone else, but I can click faster than the 'rapid' fire.
-Due to a combination of bad rapid fire and enemy spawns, you will ram into enemies in later levels.
-Upgrade screen is really clunky. Make it one screen that doesn't scroll, There really wasn't enough to warrant the scroll bar.
I really felt like I was wasting my time after stage 12. It has an interesting concept, I just don't see my self wanting to play it again.
