SlimeTROID is appropriately enough, my first submission to any game jam, and was submitted to My First Game Jam - Summer 2020. It has been a great learning experience. In both the process of actually creating a game, and getting that game available for others to play. 

I don't have a background in art, and my main goal of the jam was to create all of the art assets for the game. 

What went right

Animations -  The animations in SlimeTROID were incredibly fun to implement.  From the slime character sloshing back and forth after acting, to transforming into humanoid forms. 

In the theme of firsts, the scientist character is the first fully-animated character that I have made. She won't be winning any awards, but I'm very happy with how she turned out. 

The game is basically complete. It lacks an options menu and a pause function, but otherwise, the entire loop is present.

What went wrong

The enemies. They just don't feel that great to fight. The enemies weren't anything other than punching bags until something like day 9. A core feature of the game definitely needs to be implemented as soon as possible. They have a wander state in the code... but it just makes them stand there.

Gaining forms. Because the game lacks a centralized event system, I had to pass a lot of information to and from the enemy and their hurtbox. It works, it's just very, very bad.

The event system I implemented (the Friday before submission day) was very inflexible. Basically, it would connect exactly one thing to exactly one thing. Want to make a room where you kill two enemies to open the door? Can't. Want to make killing an enemy open two doors? Make two events. There's something like 9 events for the 3 tutorial keys appearing and disappearing. It's just silly.

If I had more time

Hit effects. 100% hit effects. Not knowing if your attacks are even hurting the enemy feels awful. 

The initial design called for three enemies (all with their own sprites and animations (oh goodness, what was I thinking?)) 
Any additional visual differences between the enemies would've been welcome. 

Overall, I consider SlimeTROID to be a success.  Sure, it could use a few gallons of polish, but I accomplished what I set out to and learned a lot.

Looking forward to the next jam.
