There are instances where tiles in the ceiling are wrong, like this:

It's also possible to clip into the ceiling by jumping up some holes without ceiling then going on top of the ceiling. Not sure if those holes are intentional.

(hole in the top left)

Also, if you dash into a wall, at the end of the dash the character will make a small jump, which actually saved me once from falling into a pit by dashing into its wall.

Thanks for submitting these! the level generation still needs some work (the tile mismatch and open holes in the level are already in my to-do list).

Can you tell me more about the dash bug? does it always happen? was it upgraded or does it happen with the regular lvl 1 dash too?

I hadn't upgraded the dash so that was with Lv1 dash, now I tried an upgraded dash and it has a few problems of its own (I don't know what the upgraded dash is supposed to do anyways).

Here's a gif of the jumping thing with Lv1 dash:

When the dash finishes completely, if it's colliding with the wall it does that little jump.

The upgraded dash does a few weird things. While airborne it apparently works fine, but if you use it standing and on the ground, it does a very short dash and stops. If you use dash on the ground while moving in a certain direction, you have an infinite dash until you stop pressing that direction. Here's a gif trying those things out:

Alright, dash bugs are fixed now (and will be fixed for you in the next release)!

The 'infinite dash' is actually intentional, if you keep running after a dash you will maintain that velocity until you stop (you can test this by jumping mid-dash while holding a direction, this will do a long jump of sorts).
