All core parts of the game work well. The controls are a little slower than I'd like, but I got used to them quickly. I like the wall-climbing; for me it's a preferable approach than wall-jumping, and it opens a lot of opportunities for exploration.

Even the basic enemies are surprisingly strong--an enemy this early in the game should not take more than 2-3 hits to defeat. Also, they should at least occasionally drop a healing item when defeated. 

Note that I ran out of health, but never died.  Either the fail state is not implemented, or it's not working consistently.

Nice, the gameplay, graphics music all work nicely!

Some thoughts:

- the attack feels a little sluggish, it's difficult to damage enemies without taking damage

- there's a few instances where I fell off-screen (like the below):

It's pretty short, but also pretty sweet. I really like specially the chill music, and the also the "home-made" sound effects wich are really fun and charming lol.

I also really loved the little Boss fight on the end, the patterns are actually really good, even if the Boss itself isn't the most polished thing in the world.

The overall combat itself feels really clanky tho, at least with the regular enemies. The character has both way too much start-lag and end-lag, so it is really hard to hit the enemies properly witouth being hit first. The enemies are also a little too fast and unpredictable, specially the guy with tentacles, there really is no clear way of knowing when he's gonna try to slap you so you just take damage completely for free.

I also think the game was very buggy for me in some aspects. Idk if other players got that too, but I was actually immortal during the entire game, no matter how much damage I took I just wasn't dying, even when I already had no hearts at all. I also didn't manage to trigger the pogo move you listed on the game page by any means, wich made me kinda sad tbh (Edit: ok I actually discovered how to do it now yay, but going back to try it again made me discover another bug: loading the save after finishing it doesn't actually works, it only loads the HUD hearts in a full gray screen lol)

I absolutely love the sounds of ghosts, they are perfect! Game feels good to control, movement upgrades are nice, was pretty short but not in a bad way, makes me appreciate it more tbh. Solid work!
