No problem, your detailed feedback is welcome and sure to be helpful ^^
well the map size is a bit large indeed, like i already joked *George Lucas voice* "I may have gone too far in a few places" i tried my best at putting some landmarks and having the compas pop up so that people could have an easier time navigating by finding the center, but i realize i clearly didn't mark well enough the use of doors and levers and even the fact that they're here at all, which was especially dumb on my part cause when the doors open they hava an animation and well they're so far from the lever that it's not even visible XD to clarify about said levers, the thing is that there's no complicated combination or anything with them, there's 3 in the map and each open a specific door, then the level design is one of the main reason that probably doesn't help with finding that out.
Still on some of the design flaws, here's how the hearts "spawn", they become visible when you are in a certain circular range from them, the main issue being that i made said range so small that you usually stay in the yellow far too long before it poping up, but then i agree i should probably change this to have them visible permanently, i initially made it like this cause i thought it might be too easy to find em lying around like that. Then the combat i mainly wanted to have the more powerful ranged enemies be a bigger threat to entice players to search for the upgrades, the other enemy may still need some tweaking but i tried to have it possible to beat without upgrades while still have them challenging enough to have a different feel while having the upgrades. And finally the lack of any kept progress upon death is just a simple oversight on my part because of the deadline, but i feel this is one of the main change i should have to ease player frustration, a main fault i'll also admit is that since i didn't anticipate well enough some of the other issues, the playtime ended up being longer than i thought to complete the game. I'll try to experiment with the fixes, minimap or otherwise but i'm taking note of everybody's feedback so far ^^
On another note, glad you still enjoyed the game despite all these issues :p
I've played my share of Diablo back in the day and i'm humble to be compared to it graphically even though i'm nowhere near the level of blizzard artists XD The repeat use of some elements is also kinda out of necessity to save time cause of the deadline but i always try to see if it looks alright before keeping it that way everytime i do something like this, and hopefully in that case it did :p and while i really love games that immerse the player in it's world, i also have a soft spot for games that have clearly "video gamey" type of items on display.
Thanks for taking time to try out my game to the end, and giving this detailed insight !
Cheers :)
