Had to admit, I was pleasantly surprised~ You truly took advantage of this mechanic with very clever puzzles! I didn't figure out that I could refill health by standing still, but after that, it was pretty interesting~ This definitely has lots of promise, well done!
Well this was heart warming. Thankyou very much :) Did you manage to get through all the levels?
Yeah, I did! There were a few times where I got myself stuck and had to replay the level from the start, so that was a tad frustrating. Especially the parts where you pick up a key, only to find out that you SHOULDN'T have, as the next area forces you to lose it! Besides the few hiccups, most of the levels were pretty well-designed, teaching the player what happens without needing text, like when you pick up the last heart. I really respected that!
It's possible I missed something, but I tried to make sure that there was always a way to escape a room or regain a key. Often it's a case of losing health to get through a door or two or losing health to drop a key (so that you can pick them up in a different order) :).
That's the odd thing: Sometimes, upon losing health and holding keys, the key doesn't drop and is lost forever. Not to mention, there's a danger of dropping keys over spikes and being unable to pick them up because you'll never have full health (although this doesn't happen in any of your levels).
