Wow, thank you so much for taking the time to complete the game in heaven, it really makes me happy ! And also thank you very much for the feedback, I appreciate that and it really helps !
The gamepad support was something I really wanted to put in the game, but unfortunately, my gamepad has been broken since a bit before quarantine, so I didn't have the time to ship one during the jam. It's absolutely on my list of priorities though ! The dash has received some complaints, and I totally hear you, but I've been playing around for some time with possible improvements, and I haven't found a way to make the input easier yet, at least not without sacrificing the ability to redirect the dash. I'm pretty sure gamepad will make it so much easier, and I'll keep trying to improve the inputs.
I had absolutely no idea about the jump issue ! Woah I'm ashamed that I let an issue that big into the game, really sorry for the inconvenience ! I thought I fixed it during development because the dash had the same issue and was fixed, but I didn't even notice the jump was acting weird too. I do multiply everything by Time.deltaTime, but I think I multiplied it twice on the jump, causing the issue. It will definitely be fixed.
About the ending, I didn't really have the time to make an entire different scene, sorry for the frustration. But there is a slight difference between the good and the bad ending, being that the corpses on the ending scene doesn't appear when you lead Abi to heaven. It makes sense with the story I wanted to tell, but I didn't put enough elements in the game to make that story undersandable. My bad, sorry.
Thank you once again for the feedback, I am working on an extended version of the game (with new environments, mechanics, etc..) which will have gamepad support and better ending scenes for sure !
