I found some really innocent glitches, like spamming buttons can sometimes result in a button being "locked", meaning that even if you are not touching the keyboard the game still thinks that you are holding down that button, and that is sometimes annoying, like when the "j" is locked and I cannot shoot anymore.
Another one that is somewhat hilarious is that when you press "r" then you die and respawn at a checkpoint, however pressing "r" before you respawn results in a small death scene where you character is not where it is supposed to be, however that is very much fine and doesn't affect the gameplay at all.
I found out that if you press "L" and a direction (left or right) while still falling from the beginning you start to slowly spin in that direction until you reach a wall, at which point you start to fall slower while still rolling midair. Also that is a soft lock if you do it to the right as you will get stuck on top of the pillar without control of the character.
To conclude this is a glitchy game and the "W" key is not mapped to be jump, which is annoying, so I'd say that this is a great game and that you have done a good job.
Keep Developing!!
