Alright mate, turns out it was on me!! I should've read the 'the interact button is that key' note on your page... Anyway, I played the game this time, died 1-2 times before completing it, that fight mechanic was a bit tough. Eventually figured it out and finished the game, but the masked guy told me -unsatisfactory-, so I thought 'hmm, maybe if I heal the zombies that can be healed, would I get a different ending?' and played through again, this time trying to use the healing mechanic too, but I got the same ending again, no idea why :P
Anyway, I think the game is really cute and nice, especially graphics-wise. Just, maybe some parts could be improved. For example, the hit feedback could be better, right now it kind of looks like the character is just waving :P. Other than that, the death feedback could also be better, maybe a fade-to-black screen or something, but right now it feels like the game just abruptly closes. Those are my thoughts!
By the way, if you have time, would you mind checking out my game too? Thanks! :>
