Here is information about clipping through tiles, some tile map structure information for Plok & files with concrete tile value map outputs of those:

Tile data (for behavior and then graphics) comes in pairs of two 1 byte addresses each, always starting with an even address. The following extracted data holds for the Normal difficulty. For the so-called ''child's play'' difficulty it may be different (but I doubt it). The concrete stage tile data layout outputs just cover the initial layouts for each stage, but the tile data can change dynamically in stages while a player is progressing through them. The intermediate vertical intersection lines are there to indicate that the right most block of tile data is not visible and inaccessible (but the level data continues into out of bounds regions to the right before it loops back to the far left in the next lower tile row), and in the boss stages 25, 29, 37, the left intermediate vertical intersection line indicates how far the screen is allowed to be moved rightwards before the respective boss battle ended successfully upon which the screen is allowed to move further rightwards. In the tile data sheet beneath there is only the even 1 byte memory addresses placed but each such even memory address represents the pair consisting of itself and the next larger (odd) memory address, and the position of each even memory address in each block in relation to other memory addresses of that block matches the position of the tile in the given stage of which the properties are determined by its respective pair of memory addresses.

One part of the idea behind this is to use this information to determine which type of diagonal slope tile (in terms of tile data values) it is for which I found a small variation of jumps that allow to clip through it on the way down when Down is held appropriately to accelerate Plok's jump downwards (and the same for other block types which may exist that one might be able to clip through, possibly using different jumps adapted to them or other means entirely). Then in the next step it can be used to find the locations of these specific kinds of diagonal slope tiles and test out clipping through them, preferably at places that may allow to get somewhere that one isn't meant to be able to get to, and in particular to clip to lower portions of stages to see if ''garbage data'' in the form of tiles is located there, such as in the case of the 2nd stage, Cotton Island Bridge:
Then the next step would be to look out for blocks there that can crash the game if one interacts with them (and possibly manipulating which blocks may be possible to be placed in such areas by the game), and to then see if ACE might be an option, and in the case this could be confirmed, there may be the outlook towards a corresponding ACE TAS, but these further aspects are just speculations so far.

Two simplified versions of working spinjumps that I found that allow to clip a block in stage 2, Cotton Island Bridge:
Frame 1: A (while facing right at correct x and y pixel position w.r.t. the clipped slope as in the image above)
Frames 42 to (52 or) 53: v (both options work, but frame 51 doesn't work anymore)
Frames 58 to 64: <v
Alternate starting position and clip jump:
Frame 1: A (while facing left at correct x and y pixel position w.r.t. the clipped slope as in the image above)
Frames 30 to 49, 50, 51, 52, 53, or 54: v
Frames 55: < (or <v, for any of the above cases)
In this 2nd case, starting to hold down at 31 doesn't work anymore.
Remark: Unpausing in this game allows to press Start to unpause the game, repress and hold Start again (within the animation time before the gameplay continues after the unpause finished) together with whatever further buttons one wants to hold, and the game will that way run the gameplay for 1 frame with the buttons that were held, and then pauses the game again, which sort of allows to easily execute even as unassisted player any conceivable input sequence for gameplay frames due to this input buffer enabling behavior (although e.g. random events or processes may still be rather uncontrollable that way).
