I think you did a good game Prinny, I was gonna give a review after I managed to beat the third creature, welp I gave up on that otherwise it would have taken me ages to do so, so that's a positive.
Your game is very nice, the amount of polish is very high (as usual), the mechanic is very nice but also very stressful, you don't know if you'll have to vent or if you're safe to attack due to the randomness of the attacks (a possible 300 damage is a bit much but it didn't happen to me so that's good lol).
Overall a very nice and enjoyable (even addictive) game, I'd play it more if I didn't want to rate other things as well! Well done! It was nice developing both of our games and chatting about it, I loved it
