going to piggy back on a lot of what im seeing in the comments. the permanent/persistent potions (eggplant/hypno spyral) are insanely annoying to deal with on the receiving end, especially the enemy who does both + expansion potions. rather than nerfing them however, another option could be to include the corruption/conversion potions in the players starting deck. This would give the player some agency in dealing with them, while still leaving it as a viable strat for players to use.
In terms of progression i would love to see some more control in how we sculpt our run. some options being providing multiple options to transform potions into, an option to add a potion w/o needing to transform, being able to use potions from our deck (but still limit the uses of the upgrades to 3 per round), or being able to remove a potion entirely.
overall a very solid start and especially impressive given the time constraint of a game jam!
