Programming Moving Spikes

Since studied blueprint in Unreal4 Engine, I am getting more and more interested in game programming.  It is so much fun because all of games are basically create by programming which is one of most significant parts for modern games.
Finally,  I created my own moving spike in my little testing level.  Here it is:

My moving Spikes are able to change the colors with they has been triggered.  Also I changed they sound when they touch the floor. Meanwhile, Camera shake will happen, too.

Tutorial Level Design - Under Sea

My level is named Under Sea.  Obviously, the location is going to be under the sea.  The idea of this design is from the cartoon of Finding Nemo.  The character is going to be like Nemo who is going to adventure in the sea.  It will meet some troubles, such as shark or spike, etc.  

I designed my game very easy in the beginning, so players can practice a little before they really get in trouble.  Then, they level is getting harder and harder.
I placed a lot of coins in the level because usually it will make player feel good and more confident.  Most of coins are located at the end of the game which will make people enhance the feeling of achievability.

Analysis of Ultimate Flash Sonic

Sonic is kind of my childhood.  I love it so much when I was young.  In this case, I am going to talk about the first level of this game which is named Chill gardens.  

In my opinion, Sonic did kind of similar thing as Super Mario that they all leave a part of level blank in the beginning of level, which is good because players are able to try to press operation keys to practice a little before get into the game.  

The layout of this level of the game is very good because the it included so many variations and other stuff which really enhanced the interest.  For example: the character can use tools that placed in the level to help the character do some actions and movements, such as springs and seesaws help jumping high,  snags can hurt the character or losing money that can be collected most of locations in the level.  

 

There are also enemies that located some places in the level, such as monkey, crab, bee and robot.  All of these enemies are kind of like barriers that really make the game so much more fun and interesting but more challenging.  

 In my opinion,  this game is pretty flexible and relax because players can so what ever they want any time and anywhere.  For instance:  The level includes different layers, you can jump to other layers and collect money first, then go back to other layers to kill enemies, or players can do opposite way.  The mode that I played has no any limit of time and the amount of money that collected.  In other words,  this level is very free.  

This mostly need handling skills of key board, but still a little luck because you will never see what is going to show up next.  

In general, I think that this level is pretty fun and familiar to me.  It is so nice to play it again.
