Things I liked:
Artstyle:
The assets you chose worked well together.
Sound Design:
The sound effects and music fit very well.
In-game Instructions:
So many games force you to consult their main page to learn the controls, it's really nice to see those put into the game itself.
Good difficulty.
Platforming difficulty was very well done, the multiple paths and varying platform sizes really made the game.
Things I disliked:
The Combat:
Combat wasn't very interesting, save a snake on a small platform who could knock you off. There wasn't anything unique about the enemies' attacks, and with a single-attack platformer like this one you really need that to make combat engaging.
Bugs:
Unfortunately, bugs were the most challenging enemy in this game. I was unable to 100% because dying once respawned me in a ghost state, where I could still die from falling, but I was immune from enemy attacks and couldn't attack them. That meant the final NPC wouldn't react with me. There was also a ladder that would freeze you halfway up, softlocking you.
Things you could do to improve the game:
Call the Exterminator.
Bugs were what dragged this game down from a four to three star rating. If those could be squished, you'd have a very respectable platformer on your hands.
Put Springs On Your Slimes:
Something that could fix your combat problem would be adding a jump attack to slimes, forcing you to dodge and seperating them from snakes.
Synopsis:
There's a lot of good potential here, and it's easy to tell that passion and thought went into this project. There's a ways to go, but with some key fixes, this game could really shine.
Thanks for your entry. :)
