Agree on the mini-map, it's way too big. In fact, after a while I was playing just by looking at the map because it was easier.
Doesn't really seem to me like you need a map for this game at all though. It's a big rectangle that's always full of coins, there's nothing there to warrant a map. And if the reason is "to see the enemies" then well, that makes the game too easy. On a related note, the score/health/time display takes up a good chunk of screen too.
I think there should be some sort of audiovisual feedback when you level up, gain health, get hurt, etc. Other than numbers changing, I mean.
There also doesn't seem to be much threat with the enemies. No reason to avoid one if it's in your way, just zoom through it to the other side. The minimal amount of damage you take is worth it to avoid turning back on the horde following behind you. Make the player bounce off of enemies when he's hit, or something like that. That would also serve as a kind of feedback.
Some ideas for different enemies:
- Enemies that bounce you away
- Enemies that hurt you and bounce you away
- Enemies that explode on contact
Also, the similarities to Ghost Shooter are rather apparent. I'm just saying. Add some new mechanics, obstacles, something to distinguish it from Ghost Shooter.
(Or maybe we need some new tutorials so that people will have a choice for other clones to make instead of just Ghost Shooter )
Some ideas for obstacles:
- Electric floors
- Bouncy bumpers (like in pinball)
- Whatever, go hog wild
Some ideas for interactivity:
- Special collectibles (big coins)
- Powerups (speed boost, invincibility, etc.)
- Make it less random (set up a level with goals other than "get points and survive." All games are about surviving, and points don't mean that much to a lot of gamers)
