Hey there, thanks for joining our jam!
The controls are intuitive, although I wish there was more visual and audio feedback. I do like its adherence to the theme, and I think it's a pretty unique take on the tower defense genre. The game runs smoothly, and the UI is simple and for the most part, does what it needs to. However, I had trouble discerning when I could put down another cyst, and it took me awhile to locate the points at the top right. It also took me awhile to figure out how much it cost to put down a cyst, since the cost was never explicitly stated anywhere, which left me confused initially. It also took me awhile to realize that the cysts themselves weren't shooting, it was the infestation damaging the enemies.
Visually, there definitely could have been more variety in background, as it was kind of bland and not particularly appealing to look at.
I spent a little over 10 minutes playing, and figured out that the enemies mostly came from the corners of the map, which left my infestation in a huge X formation instead of evenly spread out. This made the gameplay more simple, because I could just check each corner cyst, wait until it was almost dead, and then spawn another cyst, and could probably go on forever at that rate.
Great job on completing the game, and thanks for joining the jam!
