Hello everyone!
Thanks for playing and also for reporting the bugs you have found, we are only human and we do our best but some bugs do manage to slip through despite our best efforts. We have made some fixes and improvements in the last few days, which include:

There was a nasty bug where the game appeared to randomly crash during battles due to a bizarre interaction with legacy code in a text display extension, we have updated everything and disabled legacy code so *hopefully* this is solved. Apologies if you were affected by this!
Fixing Snake defensive animation
Fixed bug with Counter Attack artifact
Fixed card alpha when picking a card extremely quickly after a battle
Fixed rare crash when enemy took damage with no cards in buffer
Improved some dialogue
Fixed unnecessary delay with Resolute artifact animation
Fixed potion tooltip position in shop
Fixed enemy move tooltips not updating when stunned from certain cards

Demo Update v1.0.4
Hello everyone! We have just released version 1.0.4 for the Aventia Demo, or should I say, Cardseer Demo. As you may have noticed, we have decided to change the name of the game from Aventia to Cardseer. We believe the new name is more appropriate and fitting to the game, and we
Hello everyone!
We have just released version 1.0.4 for the Aventia Demo, or should I say, Cardseer Demo. As you may have noticed, we have decided to change the name of the game from Aventia to Cardseer. We believe the new name is more appropriate and fitting to the game, and we hope the change doesn’t cause too much confusion. The update also includes:

Overhaul to card text: You will find the card text to be more verbose and easily understandable, with less cryptic keywords.
Added status icons for some hero power effects, replacing the additional temporary text from cards
Improved tutorial graphics
Swapped the art for Honed Claw and Sharpened Claw
Adjusting position for many menu UI elements
General UI text and font improvements
General Bug Fixes
V1.0.4a HOTFIX:

Fixing bug with power card tooltips
Have Fun!
EDIT: There may be some hiccups with the demo installation if you have played prior to patch 1.0.4. If the game won't start for you, try reinstalling and that should do the trick. If you haven't downloaded the demo before this patch you should be unaffected.
