so i am looking at how the game is structured now and how it could be improved as is without much editing. here are my thoughts/suggestions:
1. each crate should drop 1 item, now this could be something the same, worse, better than you already have, or something completely new
2. some items might be cursed and become permanently equiped until the curse is removed (some curses might be kill X of Y creatures, some might make you sacrifice a certain type of item or base stat) this is to balance the item increase
3. add character levels, each level requires exponentially more XP, lvl 1 would be 1 xp, 2=2, 3=4, 5=8, 6=16...
4. each crate gives 1 XP
5. rats give 2 XP, only hit for 1, and have 1/8 your beginning health (and no armor) but do have a chance for you to miss
6. spiders give 3 XP have 1/4 your starting health, deal 1-2 damage that hits again 1-2 more turns, no armor or dodge
7. whenever you level up your health refills
8. each tile of movement rolls a D100, if the roll is equal to or less than your level you heal 1, for every 5 (10?) below that you gain another health
9. press space to wait 1 turn
10. spiders can take diagonal movement but can only move one tile a turn
11. rats take a turn to turn, and can only move straight ahead, they move 3 tiles a turn
12. you can move your level in tiles in a turn or attack with those actions or use /switch an item with those actions
13. your damage is XDY * (your level) where XDY is the damage range value of the weapon you are using (aka start with 1D1 fist X 1 level for 1 per hit)
14. wolves, 5 tiles a turn, 2D4 damage, 1 armor, no chance to dodge, beginning health
15. you may want to make some of those cracked walls into hidden passages
16. possibly start with 1 or 2 random items that lead you to begin as an adventurer
17. each level you should be able to increase 1 (your level? can be more by putting points into intelligence?) of the main stats/skills by 1
18. dead bodies should be able to be "gutted" for a chance based on skill/lvl/items to gain food, materials, and so forth, campfires/rest sites should exist to craft at/sleep at safely
19. your HP should be enough to roughly survive/mutual death being attacked on all 4 sides by creatures equal to you (rats = 1, spiders = 2, wolves [see above] like...5?)
20. you should Really have a stat counter, at least for health
