One thing that's coming: Stores that are going to sell things like consumables, and even actual health/missile upgrades. INSTEAD of selling actual items. Two types of stores, now. This might make for interesting decisions on the player's part that they need to make. Do I spend keys and credits on attacks and upgrades.... or do I need to go get a max HP boost or some missiles right now? Which room so I use a key on?
This should help correct some of this, because one way or another, in a game like this, there's ALWAYS the potential for the RNG to be a jerk.
Just thought I'd point that out since it's very relevant to this issue.
There's tons of new rooms coming in the next update, too.
