So. A while ago, while trying to prevent hogs blowtorching getting turned around, unc0rr altered the old range of blowtorch from 1/8th of 180° up or down, to a 4° gain in upwards and a -4° loss in downwards. He also made it so that starting tunnels could fail to erase sufficient terrain, trapping hogs. Here are a couple of workarounds to more closely approximate old behaviour (do some initial erasure, adjust min/max angles)

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := physlayer

LOCAL_CFLAGS := -O2

LOCAL_C_INCLUDES := $(LOCAL_PATH) $(MISC_DIR)/liblua $(MISC_DIR)/liblua $(JNI_DIR)/SDL/include

LOCAL_SRC_FILES := hwpacksmounter.c \
                   physfslualoader.c \
                   physfsrwops.c \

LOCAL_SHARED_LIBRARIES += SDL lua
