It's funny also if it's not complete! I'll surely enjoy playing it again in future if you'll continue developing it!!
Anway there are some bugs (only html5 version tested):
1) sometime with the shootgun it takes to loong to shoot and I've to click several times to make it happen
2) in the hexagone room, if I hit the left wall, I'm than stuck in that position and I can't move, only shoot!
Thanks for playing! bug number one is actually a feature xD. I made the guns reload, but didnt have time to sort out any animations/ ui / sounds for them so its really annoying to play. It actually has 5 shots before you need to reload, but its definitely something that i need to clear up. I will try to fix that wall bug thanks for reporting it!
