This is a really cleverly designed game for the following reasons:
1- It was made using Löve (I'm a sucker for bare-bones frameworks so this is totally objective and non-biased)
2- You carved the tutorial in the level using the tiles didn't you?
3- It rewards the player for randomly smashing into candles (any good rogue like should do that)
4- There are no walls, just platforms and the void so you did not even need to implement line of sight check / pathfinding (idk if that was really intentional)
5- The amounts of HP is irrelevant in a good way and the boss fight is the reward itself.
Now some things I did not like were the fact that attacking and grappling are the same action, so sometimes I'd try to hit an enemy, miss, grab a pod and perish in the void. You need to distinguish those actions. By the way the boss fight was really well-made and it was easy enough to guess what had to be done to beat it.
Nothing else to say. Would speedrun.
