Definitely. The lack of any real complexity to the level is rough. You find the key, you open a door, level done. It seems like you could make it so that you start out without a weapon or with a weapon with 0 attack, and then a weapon could become a key of sorts to open a door which would be a destructible sprite, but I haven't experimented with that yet.
Right now I have it where each level is a location in which the player must find a new insight (The key, rendered as an❗) to an overarching mystery, which allows them to leave the location. Then the end screen is a journal entry where they discuss the insight, and how it leads them to the next location.
Enemies are NPCs that demoralize the player in some way, which they can heal by seeing scenes of positivity (which are designed to funnel the player onto an invisible health pickup). They can also find scenes of negativity in the level, which gives them conviction, which is used as ammo to neutralize said NPCs.
It's a bit silly laid out without the context the audio and visuals would give to those actions, but that's the fun of limitations right?
