At least m,ake it so that there is the right chest at the same floor when we find a key. I found three golden tripple keys in one run and then two diamond keys, but no treasure chests to use them on. I threw the two useles keys into the wishing well, but only got mediocre items from diamond keys. Why not making it so that you can throw items into the well to get some exp or a random healing item? And finding a rare chest without having the chance of finding the key on the same floor nor a way to get back to collect it later is a dick move too. There was a golden chest in one of the floors, but I only found a golden triple key later.
What's up with the mystical plants? I get a lot of armor decrease while the attack increase/decrease is at least a little bit balanced out. The tips can't be read unless you take a screen shot at the right time or you are Superman or can slow down time like Quicksilver.
It's better not to pick up any plants except for the ones that heal you. Items and grinding are better ways to increase your stats. More wooden chests with keys or a healing item inside them would be nice. Stalagmites or other damaging traps right in the path so you have to ignore the monsters (my precious exp) is kinda annoying.
