I played for 12 mins and with more variety would have played for more, so if you develop it further will check it out for sure. Amazing job for a one week jam, only two things to consider:
- the monsters push the health flasks so it could get a bit frustrating to get to those, especially when more of them is pushed into the corners. if the health flasks would not collide with the monsters, the player could strategise more when get to them
- it would be great to be able to buy more than one item per shop entry. or if you want to make the choice at the shop meaningful, have some cooldown for the availability because in it's current form feels more annoyance than game design choice.
congrats on the game, hope you find the feedback useful for further developing it!
