I wasn't able to complete the game in time, so my take will be a bit limited in nature :)
In my current playthrough, I managed to experience the tutorial, strolling through the hub-ish area, obtaining the fire orb and getting game over'd atttempting to reach the lightning orb while collecting none of the secrets.
(I blame it on my bad time management, my poor skills in platforming games and watching the enemies up close for far too long... 😅)
Even if my struggle to get the platforming aspect made progress go quite a bit slow on my end, I adored the time I had in there! The tense atmosphere all around made me quite scared to move and gave me quite a bit of a shock when the enemy spotted me the first couple times, but after getting the hang of things the tense feeling quickly turned into nailing the rather tough plattforming obstacles strewing across the world! Figuring out the way to the fire orb for example had me look quite hardly to spot the blocks one can jump from to get to the upper end of the room - once again, my lack of experience can be put to blame here, but maybe including more visual types of terrain to differentiate from the stone/brick-ish look all over could help freshen up the experience and lead the eye towards the way of progress :D
Bonus points for the neat tutorial provided at the start of the game - incentivising it with a 1UP at the end does sweeten the deal of learning the controls and basic mechanics to the full effect :3
The theme of the game is neatly integrated with the other obstacle faced in the game - those pesky demons! Being able to only rely on stealth to take care of them temporarily is a great choice, for which the natural formation of the level as well as the hiding spots strewn all across can be used.
From what you might be feeling, I clearly enjoyed getting caught by the enemies 😊
Being able to see the outcome when getting caught in peace, having a movable camera to see the action from different angles and being able to skip it easily are all quite neat checks in my book! The camera movement could be made faster in my opinion, but nothing all too breaking, all things considered :)
I love the three h scenes painted there! 💖
I will be continuing my andventure in your ruin with much fun and joy and try to discover all of your secrets! Great job in crafting such a sweet game 😊
