Fun and decent prototype
As for feedback I think I would like if there were more monsters that would expand the player, instead of just taking away their HP, or somehow include the mechanic from previous game where in order to go past certain monsters or a pathway filled with monsters you would need to use a potion with you guessed it side effects and would have to manage not only your HP but your overall size.
Can't wait to see more and certainly wouldnt mind to again pay for early access updates to support future development :)
