Hello!
Here’s my version of “Glitch Garden” from the GameDev.tv Unity 2D course.
I tried to balance 10 levels on 4 levels of difficulty, and I found this game to be VERY difficult to adjust, to achieve fun and challenge for the player.
I completely changed the theme of the game. In my case I used “medieval castle” style sprites and animated characters. I added a few features, such as the attacker “tank”, life bars de-activatable by the options screen, full level music and full SFX.
I developed an SFX engine that allows you to configure the maximum allowed number of overlapped sounds for a given FX.
