Loved the art style, the player animations, the map itself! All looks AWESOME!
BUT,
The rain sure adds a lot to the experience, but perhaps it was a bit too loud.
1. The jumping mechanic feels a bit off ( I do understand that If I press the space bar for longer that the jump gets bigger but still... It's really easy to fail a jump.
2. If I get close to the side of one the platforms I can be sent flying off .
3. It's a bit difficult to see things... I was walking around the map always pressing E to make sure I got all of the items !
4. There are bits where perhaps tags were forgotten and therefore I couldn't jump when I should be able to ( There's a broken staircase where if you fall on top of it and if you don't have the kit to fix you're stuck because you can't jump )
You're onto something! Great game!
