Great game so far! The animation, music, sfx, vfx, were all so crisp.
With all the being said, during the tutorial, I got a little bit confused on the area right before the boss. I didn't we had to hit the lever to open the door. For awhile, I didn't know it was a lever, I thought it was something that was used to hold fire (that could've just been me being slow lol).
The loading times when going to the shop and different scenes were a bit slow. I will say, I was playing on the browser so that could be why. I know playing the downloadable is MUCH better lol (also a game dev).
Overall, good job on the game! I see you posting it a lot in the O & Co Games discord server. Keep it up!
