Its classic TR style from PS1, press down and you will have new menu with save/load, "e" is universal "use" button.
Of course it looks unnatural on PC.
There are two paths -right (bottom, pit) is pretty hard (that jump is impossible). The left path is better.
It is possible to finish it, the end of the map "continue..." exists (cave behind the river).
Thanks! Just finished it.
Notes to the developer:
You have a ton of holes in your map. Lower path if you jump down into the pit on the left side you can walk right out of the map. Start area left side before the first drop there is a hole between the hills. If you crouch in the river you can crawl under the wall and fall to your death. These are just the ones I found. If you die out of bounds it's impossible to evoke the ESC menu.
You HAVE to mark things like "E to save" "W or DOWN to access menu". You have to list "E to grab edge" and "X to crouch" to the 'Controls" section. Yes, some of these things are in other games or are seen as universal, but if it's not included in the 'Controls' section or stated anywhere then people don't know these mechanics exist.
The right path has either a broken jump or a nearly impossible jump. That needs to be adjusted. It's also impossible to backtrack out of the pit if you went that direction as some of the jumps are impossible when climbing back out.
Spelling/localization: It's "Title" not "Titel". It's "To Be Continued..." not "Continue...". "Continue..." implies that you have more content.
When the player dies it needs to say something on the screen to prompt the player how to proceed, maybe "E to load last save" or it should automatically load from the last save. It's ridiculous to leave her squirming on the ground indefinitely.
You need to change the logic of fall damage. It's fucked. It shouldn't be determined by what animation she's in or the amount of time the player is "falling". From what I can tell that's how it currently works. It should be determined by the distance the player falls.
That's all I can think of. Good luck.
