I've escaped!
At some point I read the comments so I spent the first two third of the game just fleeing with no equipment. Then I did the last sequence (after getting the last key, from the respawn point to the exit, getting through the camp) and the boss after equipping what I got (I think I used unknown sword, nice sword, unknown armor, unknown armor, nice armor or something like that). The encounter rate near the end sure is high.
In some way that was fun, the game controls well, plays fast enough and I enjoyed managing to get through it. I do like that you make the art yourself too and it's cool enough.
Thanks for sharing.
