Super fun game - and made in Unreal Engine too, congrats! It always surprises me how much shinier Unreal games look. The movement felt fluid, and that weird jump mechanic was actually pretty fun. That said, it might be even better if there were a bit more variety, so not every jump relied on that same weid jump. Alternatively, making the weird jump animation a little faster could help, since after a while it gets a bit tiring to wait for the character to stand up again.
One thing that confused me at the start was the ladder. Since there was no climbing animation, my first thought was, “oh, corners were cut,” which lowered my expectations a bit—which is a pity, because the rest of the game was great. Honestly, it might be better without the ladder at all. If you needed to go up, maybe moving platforms could lift the player up instead, which would avoid the need for extra animations.
Overall, I had a ton of fun playing your game, huge congrats on building this in Unreal Engine!
