Fun game! My best score was about 21000, dying at level 7 at my 3rd attempt.
I like to go in fully blind in game jam games at first to see what happens, so the first attempt it took me a bit to figure out what to do with the bombs and beams, but after that point the two-step process felt intuitive and the gameplay was challenging in a good way. Level 3 seemed like a bit of a difficulty spike, and I feel like on level 7 the screen was a bit cluttered with enemies jumping and shooting several fireballs to dodge all of it, but I like the variation in enemies and thinking of how to adjust your strategy to hit each one, which one to take out first, etc. Putting the bomb down instead of rolling it was much easier to hit the enemies with, it's a neat extra option.
The visuals were cool, and pretty detailed for a game jam imo (love the chain physics in the background).
I didn't really pay much attention to the powerups, since I was usually too busy with watching out for the enemies, so I didn't always know what the upgrades did or whether it was just a random collectible.
Also the skeleton ghost that slowly chases you is great, reminds me of the great stress of taking too long in a Spelunky level. The hitbox of it seemed a bit big though, or at least one time I died without actually touching it it seemed (?). And one time it spawned in a place where I jumped into it, so I'd add something like a warning or gradually appearing silhouette so you know to get out of the way there.
Overall I enjoyed the game! In some ways was a bit reminded of the single player mode of Towerfall (sorry to be one of those "that reminds me of" people, but it's meant in a good way).
