Personally, my favorite game so far (but that might be to the fact I love hard platformers), pretty difficult, took me about an hour to complete all the levels (reminded me of Hollow Knight's Path of Pain). Art is also pretty good, intro and ending animations were great! Movement was weird at first but I got used to it and soon liked it, and took me a while to figure out that I don't need to press ctrl to hold on to an edge.
There are 2 things I have to critque though. The first and biggest one is the lag. I think it comes from the lava but there will be parts where the fps drops signifcantly, made some deaths really annoying. 2nd is connection to theme, it's not nearly as big as the 1st problem but I feel that this was one of the game's weaker points. It would've been nice to if the terrible hero theme was incorporated into the gameplay instead of just being in the start and end.
I would love to see the lag get fixed in the future because it hindered the expierence by a decent margin. But still know I really liked the game! - (Artist from Entombed)
