Great idea, add more coins depending on the item you killed, and work on the combat a little. Also, always have a slight regeneration, and add several mini stages, with little bosses at the end. If you add a lot of stages, add a boss at the end of each stage, with a specific weak spot. Add little bonuses along the level, like maybe faster mana regeneration, or full health add a super attack, and it could destroy all the things on the current map. Take out the little shops along the way , and make one big shop. That's all I can think of at the moment, but I hope what I said helps.

I actually think this is really fun for such a simplistic looking game! With all the potential upgrades to your lil ship though it feels like you should be able to get more than 1 life or have some way of continuing. Maybe have certain enemies drop coins worth more than 1 gold or have coins worth more than 1 gold drop randomly. Aside from that the game is actually really addictive and fun to play. I'd love to see more from it.

Nice idea, but you need to work on the controls. For example, it's not too hard to allow diagonal movement, which would greatly improve the game.

This game looks like it could become a good game. You should keep working on it, because it looks as if this could turn to something really nice. The enemy spawns are random, I must admit that, and the actual changing of weapon size making the weapon change as well is a nice idea. Just make sure that the spawn rate doesn't get too out of hand and maybe add some defense boost? (Just a suggestion) Maybe make a visual effect when the charge is full. But like I said, this game has great potential. Keep up the work on this!

This game has too many rules and guidelines to remember. I enjoyed it a bit but not enough to continue playing it for more than ten minutes.
