Feedback to CIC version 0.2 prototype Thread - The Cursed Iron Cavern

The Cursed Iron Cavern (CIC) is my first project and a 2D platformer. While designing this game I followed other games like Super Mario Bros., Shovel Knight and Kirby. With CIC I combined a loot system, classic platforming and a roguelike design. Altogether the player is confronted with permanent death, different classes of enemies, a bunch of cool loot and classic platforming in randomized dungeons. But the player is also limited while playing, e.g. the player can only chose one of all known items. In CIC you play as a green slime with a huge mouth who can jump and spit sticky slime balls. Enemies in CIC are all mechanical creatures made from scrap iron and alive because they are possessed by ancient evil spirits. All enemies have different abilities.
