I'm glad you enjoyed it and like the art! Thanks for the feedback!
Item break chance is ~1% per use, so the gun blowing up soon after is really unlucky, sorry you got stuck!
The game is intentionally a bit difficult (being able to get unlucky breaks or items in the first place), but has healing fairly plentiful to try to offset some bad luck. I've gone the whole run without an item breaking and I've had it break in three uses... Stick and perfume never break if you want to give those a go without worrying about the breaking.
Do you remember what you were doing for the crash? You're the second one who mentioned a crash but I didn't run into any in the past few days of test runs so it's either a build issue or a situation I didn't get into enough...
