1. the equipment system is great but i feel like its kinda lacking, I think if you add item enhancements it could pump up the replayability of the game. A separate enhancement (not the lvl) that revolves around luck eg. +1 item enhancement if it succeeds and -1 if it fails which will increase or decrease a little bit the stats of an equipment. Also it should not use gold but a new currency or item that drops from bosses which encourage us to farm bosses instead of common monsters.
2. speaking of bosses, the ones who's in sealed chamber encounters is so hard but their rewards are rubbish especially the higher the floor we go, so how about giving us better reward for risking our current run from fighting them?? cause honestly right now i would just skip those encounters the higher I go haha
3. gold is kinda useless at the end so how about having random encounter of an equipment shop appearing the higher the floor we climb?
4. maybe add more class?
