This was hard but I ended but finishing it with 8/10 samples. However that 5 minutes adventure lasted 30 minutes...
I agree with the other people that controls feels a bit weird. I feel like it's mostly the wall slide required two keys cumulated with the fact that you have to usually switch to the opposite direction with a short timing that feels frustrating. I feel like having the wall grab on a separate key like Celeste with R1 would have made this a bit smoother.
Also I did the game with keyboard instead of controller because the menu wasn't supporting controller so I thought that for some reason it wasn't supported and didn't try it again in game. But that just me being dumb, the controller was working fine and it's easier with it (at least for me).
Last thing that was a bit weird was death being a bit long. It's a bit of a die and retry given the difficulty, so the longest it takes between death and respawning the more frustrating it is.
Despite those fine tuning, I really enjoyed the game. It's visually impacting and helps to have a good readability, music is repetitive but not tiring and helps to get "in the zone" to focus. Level design is harsh but well made and going back though previous level with new equipment felt good.
