The controls were alright and I liked the upgrades you could find, however there were several things that could use improvement. If a monster manages to hit you against a wall, your boned. There is no possible means of escape and it's an instant death. You should also add a reaction to the damage taken. With creatures such as the spiders, you take damage without being knocked back or flinching. This means unless you look at your health periodically, you might be getting killed without knowing it. Other than those tiny flaws this game was pretty fun and I enjoyed it. Keep up the good work.
