Hello,
This was a wonderful game. You took as nice mechanic, boiled it down to the most fun of it, and created a map to allow the player to enjoy it! I also appreciated the level design which is excellently done in my opinion. You know what you are doing. I also discovered several hidden paths and hidden teleports. It's pleasant to find a game that includes this hidden secrets and are implemented with good hints.
Yes, the game is difficult, but I see that it is difficult by good design, not artificially difficult due to lack of polish or due to bad desicions. You can be proud of your game and would love to know if you are developing this game further.
Also I realized that your cover image has a hint, and indeed grappling on the bats is useful!
I would be glad to keep discussing with you about game design and level design, either here or by Discord or email if you wish.
Congratulations for the entry!
Cheers
