Wow thank you so much for the amazing feedback!
The i-frame thing we heard a lot and i agree, thats definitely something well look out for in the future! The visual indicator for when the sword is ready is also a great idea, ill definitely remember that as well. We kinda focused all our time on trying (and quite frankly more often than not crashing out over) trying to do pixel art that looks passable, since this was pretty much our first time doing that and we dont have a talent for normal art either. So whenever we got something done we just implemented it and left it as is without really revisiting it. For the future actually going over mechanics and with the feedback in mind i think those annoying things can be ironed out as well. (Also of course we had to be as paleontologically accurate as possible, whenever we weren't drawing we were researching our dinos. That's also how you got the bubble shooting Spinosaur)
Thank you again for the kind words and feedback its much appreciated!
