Glad you liked the game! That's a shame that you found the music grating. The music definitely has room for improvement. If we develop the game further we might work on the music more or find existing music to use (and we'd definitely give an option to turn the music off).

Thanks for your review! Seems like the level design is our biggest complaint. We ran out of time to implement our original plan for level design (procedural generation), so we had less time for hardcoded level design and playtesting than would have been ideal. (Lesson learned for future jams, I guess.) We'll definitely keep your feedback in mind for future games and for any future work on this game.

Would you prefer being zoomed out further so you can see more tiles at once, or would you rather the platforms just be closer together? Changing the zoom and changing the level design are two different ways to fix the "leap of faith" issue, but we wouldn't necessarily have to do both to fix the issue, so I was curious if you had a preference.

Thanks for the review! I hadn't considered the pickaxe that way, since it's definitely the most tedious tool. I guess that's a balance to consider.

The inconsistency of graphics styles is because different people were working on different things (I worked on the terrain, and a different person worked on the gate and the fog). Next time we'll make sure to maintain a consistent style, possibly by having only one person do the artwork.

Sorry you had trouble with the level. I don't think of any of us have written a platformer before, so we're still new to level design and thus the levels aren't perfect. In addition, we were planning to implement procedural level generation but ran out of time, so we didn't spend as much time on hardcoding levels as a team that was planning to hardcode levels from the beginning would have.

Glad you were able to enjoy the game despite its shortcomings, and we'll definitely keep your feedback in mind for future games. (We might even use these reviews to make improvements after the voting period and share the updated version.)

Glad you liked it! The controls should work that you hold shift and then (while holding shift) press the key(s) for the direction you want to aim (the bomb doesn't need aiming, but everything else does). So if you were trying to hold directions and then press shift, then that wouldn't be registered. If you're experiencing an issue other than that, it's a bug. That's a good point about showing that shift is registered. But yeah, the controls are not necessarily the easiest to use. If we do more work on the game, we'll look into making the  controls better.

Thanks for the review! We did consider saving key progress between deaths, but decided against it because we did want there to be some kind of stakes and challenge. When you die, the tiles reset (otherwise we'd have to add another way to reset the level if you accidentally made it unplayable). So if the keys don't reset, then you don't have to find a solution that works to get all the keys; you just have to find a solution for each key individually since your key progress is restored when you die. We might develop this more after the jam, and if we do then we could add a sandbox mode so you can play with the mechanics. 

As for the fire, I did realize after making it that its use was limited. But here's a fun fact that might help you make better use of it: fire doesn't spread to empty tiles, which means if you cut off the fire (for example, by using the beam tool (#2)), you can limit the area it affects.
