Finally I Beat This Game!!!
This game is really awesome, especially because of the many different kinds of enemies and power-ups. Some parts you could improve on are putting in some more upgrades and more achievments for an extra challenge. The XP points weren't of a whole lot of use except for getting on the leaderboard, but I guess you did mention that in the instructions and I guess it was a pretty creative title other than just claiming it points. The medals were really cool although they weren't very challenging to achieve and I just wish a few more levels could be added in. Also, you lose health very quickly so maybe start off with a few more health. Bosses added in would be really cool too and sometimes it gets really easy, especially with lots of upgrades and power-ups. The artwork was brilliant, but the music I haven't listened to although I'm sure it would've been really good especially with the ability to change the song. There's not a whole lot bad about this game except a lack of challenge, but this was a really good idea after all.
P.S. I got into the leaderboard! I got 93,040 experience points in total making me into the top 50 players of all times! Am I awesome or what?
