Really like the visuals. Only thing worth mentioning is that the character sprite clashes a bit with the tiles (dunno if the palette or the amount of details is the issue)
I'd say the spiky dogs could be improved a bit, they are really tough and not even getting them on the back makes a dent on them so I just try to avoid them. Also if you just get the distance right you can kill them without any reaction from them (I think if you are above a cliff?), I'd suggest that if hit they should initiate a chase regardless of distance.
Pressing S an shift for sliding through a crack is kinda uncomfortable.
I couldn't get the grenade belt inside the cracks (skill issue?)
Boss wrecked me but I'll give it another try later.
