LD41 - KartVania

KartVania!
Combing the unlikely genres of Kart Racing with Metroidvania, explore Dracula's castle, defeat his four boss-monster generals, steal their keys, acquire upgrades to allow you to explore new areas and find secrets, and then take on Dracula himself!

Created in 48 hours for Ludum Dare 41 - theme "Combine 2 Incompatible Genres"

Controls:
Tested using an Xbox360 controller
Left stick - movement
Left Trigger - brake/reverse
Right Trigger - accelerate
A(Fire1) - fire arrows (once acquired)
B(Fire2) - jump (once acquired)
X(Fire3) - hold to skid (once acquired)
You can edit the inputs from the Unity popup. If using a keyboard, up and down should be able to be used to accelerate/decelerate instead of having to assign a button for Left/Right Triggers. On keyboard Fire1-3 are defaulted as left shift/ctrl/alt. To quit you will have to use ALT+F4 or Command Q depending on OS.

There is no save feature unfortunately, but you won't lose progress on death, you will just return to the hub area.
Also no sound, sorry about that.

Tips:
There are three optional speed upgrades hidden throughout the castle grounds
There are three optional health upgrades hidden throughout the castle grounds
You can challenge Dracula at any time, but he will be unbeatable without the treasures you can unlock by getting the keys from the four boss monsters
