Thank you for your very detailed feedback! Yes, we understand that your issues are mostly related to the game’s difficulty; most other players don’t experience these problems (in fact, we often receive comments saying the game is quite simple). In the latest version (0.8.7), we’ve significantly improved the entire combat system, and in the next version, we plan to add a difficulty level option so that every player can play in a way that’s more comfortable and enjoyable for them.
Regarding controls: yes, in the future we’ll simply add the ability to remap the control buttons. The idea about falling is good, and we might add some kind of penalty instead of death in the future. A tutorial will definitely be added to the game in future versions.
The main character has already become lighter in the latest update compared to before, thanks to improved physics.
There are two variations of the wall grab. In the simplest variation, after jumping onto a wall, you can hold down the spacebar, then release it and immediately bounce off.
