Hey thanks for playing! Your feedback is definitely valuable, quite a few changes are being implemented in V00.3 which will be the final alpha version. Definitely agree the sprint could use a little work, barely ship-able at the moment.
The boss is already being reworked, there are some scaling issues as well as you probably noticed. It takes roughly 20 shots to kill him but yes, it is possible :) Will watch your video soon when I get home to wifi, but did you find the safe in the second room? Inside resides two clips of ammo and a health pack, which are necessary to defeat the boss.
Also, saving often is recommended. Of course, crashing definitely discourages one to keep playing either way! The issue with crashes on reload I'm still trying to sort, its hard to diagnose because it varies from person to person. On some machines, it rarely crashes - if at all. On others, it seems to crash every time the game is reloaded. I don't expect you to play more, but running in compatibility mode for windows 7 seems to help.
And yes, definitely too dark. Not for long tho :)
Again thanks for the play and the video! Will check it out as soon as I get home.
