Thank you for such a detailed comment! I’m really glad you liked the enemy designs and that 'eye' effect—it’s one of those small details that really adds to the atmosphere!
Regarding the issues you found: you have a great eye for bugs. The 'disappearing items' and the 'Speed' stat it currently only determines who strikes first when a fight begins.
I'm happy to say that most bugs have been fully fixed in the V2 I just uploaded, with new death animations for all enemies and now all weapons rarities spawns in the chests.
It’s funny you mentioned the combat; we actually spent a lot of time balancing that 'semi-automatic' feel, so I’m glad you enjoyed it.
Thanks for checking out the GDD too! Hope you can give the V2 a try. :)
