Nice game! I enjoyed playing it!
Two things to note:
- The levels in the mines seem to be very laggy for some reason
- I found a bug where you have two weapons at once by picking up a gun whilst firing the first one
Aside from this though good job!
Thank you for the feedback. Very glad to hear you enjoyed it! :)
I already fixed the weapon pickup bug, we will look into the performance in the mines.
[EDIT] Just uploaded 1.0.1 with the fix for the weapon pickup.
