nice work on the game! it's got a lot of the nice sort of scaling upgrades you'd expect from a horde-survivor game (or rather risk of rain which you reference in the title xd). the upgrade ideas are fun, its just needs some more feedback and visual indicators for how far the sword swing and spin upgrades go + some other things like how much area the explosion upgrade covers. the maps look pretty neat visually, but due to the nature of wanting to charge the teleporter, most of the map gets left unexplored. risk of rain 2 incentivizes this by adding collectibles across map, but yeah thats a whole other mechanic to add for a game jam so i get it xd. i think it would still functionally work if the map was a smaller box, something like brotato maybe? but yeah took a couple of tries to beat the level 4 boss, but i managed to do so and then immediately die after looping back to the first level since i was low xd. was fun to go through, congrats on the submission!
